[Cholesterol granuloma of the temporal lobe].
Cholesterol granuloma is a histological term used to describe a non-specific inflammatory reaction produced by the presence of cholesterol crystals, which may originate a foreign-body reaction. Cholesterol granuloma of the temporal bone is silent for years and not preceded by a history of otitis media. The diagnosis is made by CT and MRI, which reveal an expansive, isodense lesion brain tissue and increased signal intensity on both T1 and T2-weighted images respectively. A case of cholesterol granuloma of the petrous apex is presented. The granuloma was excised completely using an infra-retrolabyrinthine approach.
