A rare case of giant cerebral hemispheric colloid cyst - expect the unexpected.

ABSTRACT:

Introduction

Colloid cysts are rare cystic tumors commonly located in the third ventricle. Extraventricular locations are rare, and only very few cases have been reported in the literature. These include the fourth ventricle, sellar region, cerebral hemisphere, cerebellum, brainstem, and velum interpositum. We are reporting a case of a giant right hemispheric colloid cyst.

Case description

A 75-year-old gentleman presented with complaints of difficulty in walking, swaying, and mild memory disturbances with subtle left pyramidal type of weakness. The imaging studies revealed a giant cystic lesion in the right cerebral hemisphere that was T1 hypointense and T2 hyperintense with no contrast uptake. During surgery, the cyst was suspected to be a colloid cyst since it was filled
