[Lipoma of the internal auditory canal. Report of two cases simulating acoustic neuroma].
We report two cases of intra-auditory canal lipoma, presenting as acoustic neuroma, observed in respectively 45 and 53 year old patients. Cerebellopontine angle lipomas are unusual lesions, more exceptional than their intracranial counter-parts. The knowledge of these tumoral lesions and of their close relationships with cranial nerves incite to perform a frozen section when imagery is evocative, to limit functional postoperative sequelae.
