An Interesting Case of Intracranial Epidermoid Cyst

Abstract

We report a rare case of supratentorial
epidermoid cyst with osseous metaplasia.
A 13year old girl presented with
complaints of headache and vomiting for
the past 10days and slowly progressive
weakness of right lower limb since
3years.She had undergone a right Ventriculo
peritoneal shunt for post meningitic
hydrocephalus at 1year of age. She
was symptom free till 3years ago. Investigations
with CT and MRI brain revealed
a left fronto temporo parietal large extra
axial calcified lesion with mass effect and
no surrounding edema. Provisional diagnosis
of a calcified chronic sub dural hematoma
was made. Patient underwent
Fronto temporoparietal craniotomy and
evacuation of contents and total removal
of capsule. Histopathological examination
revealed an epidermoid cyst with
features of osseous metaplasia.
