title: Ruptured intracranial dermoid cyst.
abstract: Intradural dermoids are rare congenital tumors representing approximately 0.05% of all intracranial lesions. These benign tumors have a typical appearance on CT and MR due to their lipid components. The complication caused by rupture are the spillage of the fatty material into the cerebrospinal fluid. We report a case of a ruptured dermoid cyst showing fat/fluid levels in both side ventricles and fatty material in the subarachnoid space on CT and MR-imaging and the follow-up over four years after incomplete resection of the tumor.
