The effectiveness of anthelminthic and corticosteroid drug therapy in parenchymal neurocysticercosis is well established. The treatment of parenchymal solitary cysticercus granuloma (SCG), however, remains controversial. We attempted to obtain a consistent estimate of the efficacy of anthelminthic and corticosteroid drug treatment in SCG.


Randomized-controlled trials (RCTs) comparing rates of seizure freedom, granuloma resolution, and residual calcification in individuals with SCG treated with anthelminthic or corticosteroid drugs with those treated with antiepileptic drugs (AEDs) alone were systematically reviewed and quantified using fixed- or random-effects meta-analysis.


Fifteen RCTs were identified for inclusion. Ten RCTs assigned 765 people with SCG to AED treatment with or without anthelminthic drug (albendazole) treatment. A further 5 RCTs assigned 457 people with SCG to AED treatment with or without corticosteroid drugs. Anthelminthic treatment was associated with significantly increased rates of seizure freedom (nonevent odds ratio: 2.45; 95% confidence interval: 1.49–4.03; p = 0.0004) and significantly higher rates of granuloma resolution (odds ratio: 2.09; 95% confidence interval: 1.41–3.00; p = 0.0003), but did not alter the risk of residual calcification. Corticosteroid treatment was not significantly associated with any outcome.


Anthelminthic treatment with albendazole provides improved rates of seizure freedom and hastens resolution of the granuloma. The role of corticosteroid treatment remains uncertain. The benefits (or lack thereof in the case of corticosteroids) are consistent when measured across different time points after treatment.

Neurocysticercosis is a common parasitic infestation of the CNS and is possibly the most common risk factor for acquired epilepsy worldwide.1 The infestation is widespread in most resource-poor countries.2 It is also being diagnosed with increasing frequency in high-income countries, especially in those with a large number of immigrants, such as the United States.27

Seizures are the most common manifestation of neurocysticercosis and are caused by the helminthic larvae which, on entering the brain, form cysts. These cysticerci subsequently degenerate, triggering a local host inflammatory response, and eventually resolve with or without calcification. The severity of brain infestation ranges from a single lesion to hundreds.8,9 Treatment differs for multiple and solitary parenchymal cysticercosis as well as for different stages of the cysticerci in the parenchyma. There is evidence to support the use of anthelminthic treatment together with corticosteroids in individuals presenting with multiple viable cysts.1013 The roles of both anthelminthics and corticosteroids in the treatment of solitary cysticercus granuloma (SCG), however, remain uncertain.8 Several randomized-controlled trials (RCTs) of anthelminthic drugs and corticosteroids have been conducted in SCG, but most were small. We systematically reviewed all available RCTs of anthelminthic drugs (either albendazole or praziquantel, the only 2 anthelminthics available; alone or with corticosteroids) and corticosteroids alone (without anthelminthic treatment) in SCG. We sought to identify the best strategy for treatment of SCG.


Information sources and search

RCTs were identified by searching electronic databases and reference lists of articles with no time or language restriction. Detailed information on the databases used and the search strategies is provided in appendix e-1 on the Neurology® Web site at The eligibility criteria for the RCT inclusion are provided in appendix e-2.14,15

Methods of analysis

All data were entered in RevMan version 5.1.6 for analysis ( Significant heterogeneity between studies was defined by p value <0.1 using the χ2 test or an I2 >50%. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel method, followed by fitting fixed- and random-effects models. We used the random-effects model results if there was evidence for heterogeneity between RCTs, because this provides a more conservative effect than the fixed-effects model.


RCT selection

The search identified 235 citations (figure 1). After adjusting for duplicates, 200 remained. We excluded 169 because they were reviews, case reports, letters to editor, editorials, case series, retrospective studies, nonparenchymal neurocysticercosis studies, or active comparator trials (comparing 2 agents, e.g., albendazole with praziquantel). Full texts of the remaining 31 were reviewed; 16 were excluded because these contained data previously published,1618 4 RCTs studied agents other than anthelminthics or corticosteroids,1922 5 included patients with multiple enhancing or cystic lesions,13,2326 and 4 had no control group for comparison.2730 Eventually, 10 RCTs, involving 765 subjects with SCG, were included in the meta-analysis of anthelminthic treatment.3140 In one of these, some subjects had 2 rather than a single enhancing lesion.36 We chose to include this trial because the proportion of subjects with 2 lesions was small (18%). Five RCTs, involving 457 people with SCG, were included in the meta-analysis of corticosteroid treatment.e1-e5

Flow chart of the literature search

Because the outcome assessment was performed after different periods of follow-up (mostly 3, 6, 9, and 12 months after intervention) in the various trials and resolution rates for SCG are directly related to the duration of follow-up,21 the meta-analyses for each of the outcome parameters (including seizure freedom during follow-up, complete granuloma resolution, and residual calcification) were undertaken separately for 3, 6, 9, and 12 months of follow-up. A combined analysis regardless of the time point of outcome assessment was also undertaken for both agents and all outcomes. Features of the included RCTs are provided in tables 1 and 2.

Seizure freedom with anthelminthic treatment

The proportion of subjects with seizure recurrence on antiepileptic drugs (AEDs) after therapeutic intervention with anthelminthic drugs was reported for 3-month follow-up in 2 RCTs,32,36 6-month follow-up in 5 RCTs,33,35,36,39,40 and 12-month follow-up in 1 RCT.34 This information could not be extracted from one of the reports but was obtained after contacting the authors.34

The proportion of subjects who remained seizure-free was significantly higher in the anthelminthic-treated group compared with controls for 3 months follow-up (nonevent OR [i.e., 1/OR for seizure recurrence]: 4.05; 95% CI: 1.76–9.33; p = 0.001; I2 = 0%), but not for 6 months (nonevent OR: 1.79; 95% CI: 0.95–3.38; p = 0.45; I2 = 0%) or 12 months (nonevent OR: 0.64; 95% CI: 0.19–2.17; p = 0.47; heterogeneity not applicable) (figure 2A).

Pooled analysis of the data from various RCTs reporting outcome at 3, 6, and 12 months of follow-up revealed significant heterogeneity (I2 = 68%); no heterogeneity was found among trials restricted to 3 and 6 months (I2 = 1%). Meta-analysis of the pooled data from trials reporting outcome at 3 and 6 months revealed significantly higher seizure-freedom rates in the pooled anthelminthic-treated group compared with the pooled controls (nonevent OR: 2.45; 95% CI: 1.49–4.03; p = 0.0004). One RCT in this pooled analysis reported seizure outcome both at 3 and 6 months,36 but removal of this did not substantially affect the pooled nonevent OR (2.00, 95% CI 1.14–3.52, p = 0.02, I2 = 0%; and 2.24, 95% CI 1.27–3.95, p = 0.005, I2 = 12% at 3 and 6 months, respectively).

Granuloma resolution with anthelminthic treatment

Seven RCTs reported rates of granuloma resolution based on contrast-enhanced CT scan and 1 on MRI performed at 3 months after intervention.31,32,34,3640 Five RCTs reported resolution at 6 months follow-up time using CT31,33,35,39,40 or MRI acquisition.34 All CT studies but one35 used contrast-enhanced acquisition. The MRI study included gadolinium-enhanced images.34

We found significant heterogeneity among RCTs at the 6-month follow-up time point (χ2 p = 0.04; I2 = 57%); therefore, random-effects analysis was used to pool the rates of granuloma resolution in the RCTs (figure 2B).

Separate analysis at 3 and 6 months follow-up time showed a significantly higher rate of granuloma resolution in the anthelminthic group both at 3 months (OR: 1.87; 95% CI: 1.24–2.82; p = 0.003; I2 = 0%) and 6 months (OR: 2.43; 95% CI: 1.09–5.41; p = 0.03; I2 = 57%). Four of the RCTs reported granuloma resolution rates at multiple time points of follow-up and hence had a repeated-measures design.31,34,39,40

A significantly higher rate of granuloma resolution was observed with anthelminthic treatment in the pooled analysis of data from 3 and 6 months (OR: 2.09; 95% CI: 1.41–3.09; p = 0.0003; I2 = 31%).

When trials with repeated-measures design were excluded from analysis, the ORs for granuloma resolution remained increased in favor of anthelminthic treatment both at 3 months (OR: 2.25; 95% CI: 1.43–3.52; p = 0.0004; I2 = 12% (data removed from 6 months) and 6 months (OR: 2.10; 95% CI: 1.28–3.47; p = 0.004; I2 = 41%).

Residual calcification with anthelminthic treatment

Five RCTs reported residual calcification on follow-up imaging as one of the outcomes.3235,40 Two RCTs reported residual calcification at 3 months follow-up,32,34 and 4 reported the outcome parameter at 6 months follow-up.3335,40

No significant heterogeneity among the RCTs was detected (I2 = 0%). We found no significant difference between the treated and control subjects regarding the proportion of subjects with residual calcifications in the pooled analysis using fixed-effects analysis (OR: 1.00; 95% CI: 0.59–1.70; p = 0.99).

Seizure freedom with corticosteroid treatment

One corticosteroid treatment RCT reported rates of seizure recurrence over 3 months of follow-up,e3 2 over 6 months,e1,e3 and 3 over 9 months follow-up time.e2,e4,e5 We used random-effects analysis to test differences between the pooled treated and controls because significant heterogeneity was present in the overall analysis (I2 = 64%). One RCT appeared twice in the pooled analysis because of its repeated-measures design.e3

The single RCT reporting seizure recurrence over 3 months of follow-up time showed no significant difference in the rates of seizure recurrence between corticosteroid-treated and control subjects (nonevent OR: 1.02; 95% CI: 0.06–16.81; I2 not applicable) (figure 3A). At 6 months, a significantly lower rate of seizure recurrence was found in the corticosteroid-treated group (nonevent OR: 5.97; 95% CI: 1.99–17.88; p = 0.001; I2 = 0%). No significant differences between the treated and control subjects were found in the 3 RCTs that followed subjects up to 9 months (nonevent OR: 0.99; 95% CI: 0.34–2.85; I2 = 66%). We did not pool subgroups because of between-trials subgroup heterogeneity (I2 = 64.7%).

Granuloma resolution with corticosteroid treatment

Five RCTs measured the effect of treatment with a short course of corticosteroids alone (standard AED treatment) on granuloma resolution.e1–e5 Three RCTs reported rates of granuloma resolution at 3 monthse2,e4,e5 and 3 at 6 monthse1,e3,e5 of follow-up time. One RCT used a repeated-measures design with different modalities, CT at 3 months and MRI at 6 months.e5

A random-effects analysis (performed because of significant heterogeneity; I2 = 74%) did not reveal any significant difference in the rates of granuloma resolution over 3 and 6 months as well as in the overall combined analysis (OR: 1.82; 95% CI: 0.88–3.77; p = 0.11) (figure 3B). This nonsignificant pooled effect remained using a sensitivity analysis when the repeated-measures data were excluded from the 3-month analysis (OR: 1.99; 95% CI: 0.79–5.04; p = 0.15) and the 6-month analysis (OR: 1.98; 95% CI: 0.78–5.00; p = 0.15).

Residual calcification with corticosteroid treatment

Three RCTs of corticosteroid in SCG reported rates of residual calcification on follow-up imaging studies.e2,e3,e5 The proportions of subjects with residual calcification on follow-up imaging were similar in the 2 pooled groups using fixed-effects analysis (OR: 1.18; 95% CI: 0.54–2.56; p = 0.68; I2 = 0%). Subgroup heterogeneity was not significant (p = 0.25; I2 = 25.7%).


The treatment of SCG mainly comprises the use of 3 different classes of drugs, i.e., AEDs, anthelminthic drugs (albendazole and praziquantel), and corticosteroids. Using AEDs to prevent seizures is standard practice. The use of anthelminthic agents and corticosteroids (alone and in combination with anthelminthic agents) is based on sound rationale of the biology, natural history, and symptomatology of the cysticercus located in the brain parenchyma and previous experience of their use in live, active cysticerci.13

The efficacy of anthelminthic drugs in live, vesicular, and active parenchymal cysticercosis has been established.1012 These drugs were originally used to treat live, active cysticercosis but their use was later extended to treatment of SCG based on several small, uncontrolled trials.e6–e8 The earliest RCT of anthelminthic treatment (albendazole) in SCG found no difference in the frequency of resolution of the granuloma at 3 months among those who were treated with albendazole compared with those who were treated with nonspecific therapy (i.e., AEDs).37 Since this initial RCT, several RCTs of anthelminthic treatment in SCG have been undertaken, providing conflicting results.32,35,36 A meta-analysis of RCTs of albendazole in people with 1–2 parenchymal granuloma was reported in 2006.11 It failed to demonstrate a better resolution rate with the use of albendazole (OR: 1.18; 95% CI: 0.82–1.71; p = 0.38). A recalculation after excluding 1 trial with an outlier OR, however, suggested that albendazole improved resolution of the granuloma (OR: 1.93; 95% CI: 1.21–3.08; p = 0.006). The meta-analysis pooled various RCTs regardless of follow-up period and the time period of outcome assessment, which varied from 3 to 15 months. Since this meta-analysis, more RCTs have been undertaken.18,31,33,38,40 This prompted us to undertake the current study. It is also different from the previous study because we analyzed pooled data according to the time of outcome assessment in the component RCTs (i.e., 3, 6, and 12 months). The rationale for analyzing resolution rates in the pooled data according to the follow-up period after which outcome assessment was performed is that rates of natural resolution (without intervention) vary as a function of time period of follow-up. One prospective study of 210 people with an SCG followed-up after their first seizure estimated resolution rates on follow-up CT of 19% at 3 months, 36% at 6 months, and 63% at 1 year.21 Thus, the chances of resolution of the SCG increase with longer follow-up. Compared with the earlier meta-analysis, our study conclusively established the benefit of anthelminthic treatment with albendazole both at 3 and 6 months and in the overall pooled analysis.

The benefits of anthelminthic treatment were also evident when seizure freedom was used as an outcome because the proportions of subjects who remained seizure-free over 3 and 6 months of follow-up were significantly higher in the albendazole-treated group (figure 2A). Because SCGs might resolve with or without calcification and the presence of residual calcification is associated with the occurrence of seizures, especially in the long-term,e9,e10 we also analyzed the effect of albendazole treatment on the frequency of residual calcification on follow-up imaging. There was no evidence, however, for either an increased or decreased risk of residual calcification associated with anthelminthic treatment in the pooled analysis.

It may be concluded that although the treatment of degenerating cysticercus granulomas is counterintuitive from a theoretical (biological) point of view because the cysts are already being destroyed by the host immune system, the significantly improved resolution rate of the granuloma and better seizure-freedom rates with albendazole treatment suggest that anthelminthics might hasten the involution of the granuloma as well as offer the clinical benefit of improved possibility of being seizure-free.

This is the first meta-analysis of corticosteroid treatment in SCG. The administration of a short course of corticosteroids in conjunction with anthelminthic treatment to control edema and symptoms due to the host inflammatory response to neurocysticercosis is common practice. Likewise, anecdotal observations of the benefits of corticosteroid treatment regarding amelioration of certain manifestations (including seizures and headache) attributable to the inflammatory degeneration of SCG prompted several RCTs of a short course of corticosteroids (typically 2 weeks) alone (i.e., with AEDs but without anthelminthic therapy) in people with this type of neurocysticercosis.e1–e4 We identified 5 RCTs of a short course of corticosteroids in subjects with SCG for this meta-analysis. Nearly all of the RCTs included small numbers of people. The trials also differed in treatment protocols used (e.g., the corticosteroid agent used, route of administration, and timing of treatment) and design (times of follow-up and outcome assessment). Some, but not all, RCTs suggested benefits of corticosteroid administration. We found no overall significant difference in the rates of seizure freedom, granuloma resolution, or residual calcification between the corticosteroid-treated and control subjects. This lack of benefit of corticosteroid treatment on various outcomes is an important finding in guiding treatment policies for SCG. Theoretically, administration of corticosteroids alone, which is purported to suppress host inflammatory response to the degenerating SCG, is counterintuitive and in conflict with the practice of using albendazole in SCG. The latter hastens resolution by promoting degeneration of the SCG and has clearly been shown to improve outcome. Corticosteroids are useful in the management of inflammatory symptoms in multiple neurocysticercosis, but the lack of benefit in solitary lesions as we have shown might be due to a milder inflammatory response triggered by a single degenerating cysticercus as opposed to many. Whether using a short (2-week) course of corticosteroids would be expected to have any effect on seizure recurrence and granuloma resolution in the long-term (i.e., over several months) is a matter of speculation.

Our study has limitations. Many of the RCTs involved small numbers. There were also considerable differences among trials in the population sampled (differing selection criteria [some included only children] and differing time between first seizure and treatment onset), treatment protocols (choice, dose, timing, and duration of treatment), and study design (timing and methods of outcome assessment and duration of follow-up, AED protocols, and documentation of seizures). Hence, the results were prone to heterogeneity because of selection of participants from different study populations and the variable delay between infection and treatment across various studies.27 The period of follow-up in the trials was also variable, which increased heterogeneity in the pooled analysis, although we tried to separate the early from the later follow-up time points. The quality of some of the RCTs regarding reporting of randomization techniques, outcome assessment, and blinding was poor. Most trials used CT for outcome assessment and its limitations must be considered. A single enhancing lesion on CT might encompass different stages of an involuting cysticercus including a cystic (or late vesicular or colloidal) or nodular (granulomatous) stage. There is evidence from trials of multiple neurocysticercosis that cystic lesions respond better to albendazole than granular-nodular stages. MRI offers the advantage of being able to differentiate better between cystic and granular cysticerci and therefore provide insights into effects of treatment on subgroups divided according to the stage of SCG. To our knowledge, outcome assessment stratified according to the stage of the single parenchymal cysticercus has not been undertaken so far. An additional source of variability among studies could be the imaging modality, because 2 RCTs used MRI,34,e5 which has a different contrast-to-noise ratio from the CT scans used in the majority of the RCTs.

Despite limitations, our study provides support for the use of albendazole (with or without corticosteroids) in the treatment of SCG because it offers increased possibility of seizure freedom and improves rates of granuloma resolution. However, the pooled evidence does not confirm a beneficial effect of the administration of corticosteroids alone in the treatment of SCG. We recommend the use of albendazole (with or without corticosteroids) in the treatment of SCG.

Ideally, however, large, multicenter, multi-arm RCTs comparing the efficacy of albendazole (with and without corticosteroids) and corticosteroids with placebo are required to confirm our findings and to clarify the exact contributions of anthelminthic therapy, corticosteroids, or their combined regimen in long-term seizure recurrence, granuloma resolution, and residual calcification.
