Abstract

|
|
|
Most of intradural epidermoid cyst arise as slowly growing extraaxial lesions but purely intracerebral epidermoid cysts are rare. A 39-year-old female presented with a headache during several months. Brain computed tomography (CT) scan showed a mass lesion in the both frontal lobe with heterogenous density approximately 5×5cm in size. Magnetic resonance imaging (MRI) revealed a mass of heterogenous signal intensity on T1, T2-weighted image and faint enhancement with gadolinium (Gd). Through the both interhemispheric approach, mass was removed subtotally except the calcified portion tightly attached to the corpus callosum. The patient discharged without neurological deficit. The authors report a case of epidermoid cyst in the corpus callosum and discuss the pathogenesis of the intraparenchymal epidermoid cyst.
