Associated olfactory groove meningioma and acoustic neurinoma.
The authors describe the case of a 71-year-old man without signs of phacomatosis with a history of progressive psychomotory lowering and two simultaneous tumors of the olfactory groove and of the cerebellopontine angle, as demonstrated by CT scans. Histologic examinations showed the lesions to be a meningioma and a neurinoma. The rarity and the possible pathogenesis of this association are discussed.
