Abstract:
We reviewed 6 epidermoid and 3 dermoid tumors of the brain treated surgically for a period of 4 years. The favorite sites for epidermoids were the cerebellopontine angle, whereas dermoids were found in the cerebellar vermis. The average age was 44.2 years for the patients with epidermoid tumors and 24.6 years for the patients with dermoid tumors. Average duration of symptoms was much shorter in dermoids than in epidermoids. Computed tomography scans revealed hypodense lesions with irregular borders without contrast enhancement. Magnetic resonance imaging was performed on 3 patients;the tumors showed decreased signal intensity relative to the brain on T1-weighted images and increased signal intensity relative to the brain on T2-weighted studies. Five were removed totally and 4 subtotally. Aseptic meningitis and transient facial nerve palsy were causes of postoperative morbidity.
