[Subarachnoid hemorrhage as the 1st clinical manifestation of neurinoma of the acoustic nerve].

The association of sub-arachnoidal hemorrhage and benignant tumors of the pontocerebellar angle represent a rare event. The authors describe a case of neurinoma of the acoustic nerve which revealed itself with a sub-arachnoidal hemorrhage. After recalling the other only observation reported in literature, the authors discuss both its clinic and etiopathogenesis.
