[Aneurysms of the auditory artery at the internal acoustic meatus]

Aneurysms of the anterior inferior cerebellar artery at the origin of the internal auditory artery are uncommon. Up to the present time 14 cases have been published, and in twelve of these operative treatment was undertaken. We now present a Fifteenth case which was operated on thirty hours after the subarachnoid haemorrhage had occurred and was treated with the calcium antagonist Nimodipine. The clinical course, the neuroradiological findings and the operative situation are presented.
