Huge Meningiomas

A Review of 93 Cases


Between 1972 and 1996, 450 consecutive patients with intracranial meningiomas were operated on at Çukurova University School of Medicine. By size, intracranial meningiomas were classified as huge (>6 cm minimum diameter when extrapolated to anatomic size) or not huge (<6 cm). The present study involves 93 patients who underwent 109 craniotomies for the removal of huge meningiomas. All patients are adult, with 31 men and 62 women or a 1:2 male to female ratio, with a mean age of 48.7 ± 2.3 years at the time of diagnosis. The average duration of observed survival in 85 patients followed in the computed tomography (CT) era was 4.8 years and that of 8 patients in the pre-CT era was 8.8 years. Eleven patients died by the last follow-up assessment. Seventy-nine patients were still alive at the last follow-up assessment. The overall postoperative mortality rate was 3.2%. The overall recurrence rate was 19%. In descending order of frequency, the first five anatomic locations of the huge meningiomas were the parasagittal region in 18 patients (19.3%), the cerebral convexity in 15 (16.1%), the olfactory groove in 15 (16.1%), the falx in 12 (12.9%), and the tuberculum sellae in 11 (11.8%). The overall results of surgical treatment in 93 patients were total removal in 59 (63.4%), radical subtotal in 18 (18.3%), and subtotal in 16 (17.2%), with good outcome in 69 (74.1%), fair in 16 (17.2%), and poor in 5 (5.3%). In conclusion, the huge size of meningiomas affects the extent of removal, recurrence rate, postoperative outcome, operative morbidity and mortality rates, and survival time negatively.
