Abstract

An adult female with underlying Major Depressive Disorder presented with recurrent depressive episodes and altered behaviour. Plain CT and MRI showed right middle cranial fossa lesion with a typical CT and MRI features of ruptured dermoid cyst.Intracranial dermoid cysts are uncommon lesions with characteristic imaging appearances. They are rare, benign, congenital, slow-growing cystic lesions. On imaging, they are usually well-defined lobulated, midline masses that have fat density on CT and high signal intensity on T1-with variable signal onT2-weighted MR images, unlike intracranial lipomas, which follow fat density on all sequences. Rupture of intracranial dermoid cysts is a relatively uncommon phenomenon and characteristically associated with fat density material in the subarachnoid spaces, such as intraventricular fat-fluid levels or fat globules in the sulci. It can cause serious complications such as chemical meningitis, vasospasm, and cerebral infarction. MRI is a modality of choice to assess the extension of complications.
