Ruptured central nervous system dermoid cyst of the suprasellar region manifesting as unusual epileptic seizure: a case report.

Central nervous system dermoid cysts are very rare lesions derived from ectopic epithelial cells. They are slow-growing benign tumors, but may cause significant morbidity through compression of neurological and vascular vascular structures and, rarely, rupture into the subarachnoid space. We present a rare case of a spontaneously ruptured intracranial dermoid cyst in a 32-year-old man presenting as new onset epileptic seizures due to chemical meningitis caused by dissemination of fat or lipid droplets.
