Oiled Brain and Status Epilepticus: Intraventricular and Subarachnoid Rupture of a Temporal Dermoid Cyst

Abstract

Intracranial dermoids are rare slow-growing tumors. Generally, they are revealed after they reach a considerable volume, leading to the compression of neural structures. Exceptionally, these inclusion tumors can rupture spontaneously within the subarachnoid, intraventricular or subdural spaces. We present the case of a ruptured temporal dermoid cyst with intraventricular, subarachnoid and subdural spread, revealed by status epilepticus in a 25-year-old woman. The treatment of such tumors should be surgical, with the aim of a total removal when feasible. Recurrence of subtotally removed dermoids remains exceptional. The chemical irritation of the cortex but also the vasospasm induced by the fat droplets spread might induce seizures.
