[Ruptured dermoid cyst].

We report the case of a 28-year-old male admitted to the emergency department for generalized seizure. A brain computed tomography (CT) revealed a ruptured dermoid cyst of the supra-tentorial stage (multiple drop-shaped fat structures were found in the subarachnoid space, basal cisterns and in ventricular system). An additional magnetic resonance imaging (MRI) was conducted to confirm the CT findings.
