Analysis of giant intraventricular and extraventricular epidermoids, defining risk factors for recurrence, an institutional experience

Abstract

Although the intracranial epidermoid is known to recur after long interval, tumor with specific characteristics can recur in short span of 5-6 years. Tumor characteristics such as preoperative capsular enhancement, multicompartmental distribution in vertebrobasilar territory, large size, and presence of calcification are strong predictors for recurrence. Performing endoscope-assisted microsurgery can decrease the postoperative morbidities but does not reduce the recurrence risk.
