Atypical Intracranial Epidermoid Cysts – Radiological Diversity

Manish Baldia,Edmond Jonathan.G,Krishna .

Abstract


Abstract The main objective of this paper is to focus on the cause of diversity in MR appearance of the epidermoid cyst.  We report 3 cases of epidermoid cysts which had an atypical appearance on radiology and mislead the diagnosis. We   present the clinical presentation imaging and pathological findings in three patients with atypical epidermoid cysts. The radiological findings of the first case were in favour of  dermoids, the second case was in favour of a high grade glioma with bleed, and the third case was white epidermoid. The various theories for the divergent radiological appearance were explained with literature review.
