@entity4890 or cholesteastoma is a @entity66 . It usually arises in the paramedian cisterns of the posterior fossa. Its incidence varies between 0.2 and 1% of all @entity5 . The cerebello-pontine angle (CPA) is the most common localization. Our study reports 10 observations of CPA @entity4890 , treated in our department between 1989 and 1999. The age of our @entity1 ranged from 20 to 45 years, with male predominance. The @entity1 were admitted with symptoms of @entity3308 or signs of @entity6804 . CT-scan was performed in all cases and MRI was performed in 5 @entity1 . The audiometric explorations only provided an orienting contribution. Treatment was exclusively surgical. The retro-sigmoid approach was used in 6 cases, the sub-occipital in 30% and a subtemporal approach in one case. Total resection of the @entity4890 was accomplished in 4 cases, and subtotal resection in 4 cases. Two @entity1 underwent partial resection and underwent a revision procedure. The histological examination showed an @entity4890 in all cases. The clinical course was controlled in 6 @entity1 : 4 @entity1 recovered and became symptom free. A persisting @entity51 was observed in two cases ( @entity393 , @entity7364 ); 4 @entity1 were lost to follow-up. @entity4890 is a @entity5 . Total resection is the ideal treatment, but we have to be aware, taking into consideration the adherence of the @entity5 to @entity531 , of the risks at attempting total resection.
