Patient with Epilepsy Caused by the Spontaneous Rupture of an Intracerebral Dermoid Cyst.

Abstract

This is a rare case of a patient presenting with epileptic seizures and headaches who was diagnosed with spontaneous intracerebral dermoid cyst rupture via radiographic imagery, and rupture was confirmed via a pathology report. We report the case of a woman aged 26 years who presented with a history of chronic headache for 9 years without other symptoms, and progressive worsening of her headache had occurred for 1 month prior to admission. Radiologic examination showed a large mass located in the left temporal fossa and a large amount of homogeneous matter in the subarachnoid space of the ipsilateral cerebral hemisphere, then the tumor was completely excised. A left pterional craniotomy was conducted under general anesthesia for removal of the tumor, and pathological examination showed a dermoid cyst. We discuss the clinical and radiologic features, as well as the treatment of this patient.
