title: Supratentorial dorsal cistern epidermoid cyst in childhood.
abstract: Epidermoid cysts (ECs) are rare developmental lesions occurring anywhere along the central nervous system. Usually affecting adult patients, the occurrence of supratentorial dorsal cistern ECs has been reported in only 1 certain case of pediatric age. An additional pediatric case is presented. An 11-year-old boy had an 8-year history of petit mal seizures. Neurologic examination on admission was negative. T1-weighted magnetic resonance images demonstrated homogenous, hypointense, intradural, extracerebral, right frontal, precentral, parasagittal mass with relatively high signal intensity on T2-weighted images. The lesion was completely removed using a microneurosurgical technique with special care taken with regard to the adjacent nervous and vascular structures. Histologically, an EC was diagnosed. The patient had no recurrence for 2 years and seizures were significantly reduced. This case suggests the need to include ECs in the differential diagnosis of intradural supratentorial extracerebral lesions in childhood.
