BILATERAL CHOLESTEROL GRANULOMAS OF THE TEMPORAL BONE

Cholesterol granulomas of the temporal bone without clinical symptoms of chronic otitis media may result from an indolent inflammatory proce ss caused by a congenitally blocked group of air cells. A unique case of giant bilateral cholesterol granulomas of the temporal bone is pres ented to support this theory. Management allowed bilateral surgical re moval with hearing preservation. The differentiation between cholester ol granuloma, giant cholesterol cyst and other lesions of the temporal bone is discussed, The presumed pathogenesis of this condition is rev iewed.
