Intracranial Convexity Lipoma with Massive Calcification: Case Report

Intracranial lipoma is a rare disease entity accounting for about 0.1-0.5% of all intracranial tumors. More than 50% of intracranial lipomas are located in the callosal cisterns (1-3). Intracranial lipomas are also found in other locations including the quadrigeminal, superior cerebellar, suprasellar, interpeduncular, cerebellopontine angle, and Sylvian cisterns (4-6). An offmidline location of an intracranial lipoma is uncommon (3, 7, 8). We report an intracranial lipoma with an unusual location in the high parietal convexity along with massive calcification and no underlying arteriovenous malformation or congenital anomaly.
