Vasospasm after acoustic neuroma removal.

A case of a acoustic neuroma with a two-stage removal due to severe bleeding is presented. The patient remained drowsy after the second operation and by the 8th day deteriorated quickly with progressive right hemiplegia and aphasia. The cerebrospinal fluid was bloody, vasospasm was shown in the angiograms, and an ischemic area was disclosed in the computed tomography scan. The outcome and the neuroradiologic examinations suggested that blood in the basal cisterns caused the vasospasm and the brain ischemia. A review of the literature disclosed only one similar case.
