A Postoperative Venous Hemorrhagic Infarction of Cerebellopontine Angle Tumor:1 Cases

ABSTRACT

The authors present a case of cerebrellar venous hemorrhagic infarction which developed after removal of a cerebellopontine angle meningioma. The clinical course was rapidly fatal inspite of an aggressive management including surgical decompression beginning from 30 minutes after complete recovery from anesthesia. The brain C-T scan showed flame-shaped subcortical hemorrhage which is known to be a typical finding of a venous hemorrhagic infarction. The causes may be two foldOne is the cautrization and resection of multiple petrosal veins which were inevitable because of a bleeding from the vein and the other is the venous congestion caused by the compression of an internal jugular vein in oblique supine position. Reminding of one or oth of the above possibilities whenever we are performing surgery around the superior petrosal vein may help us to prevent the rare but fatal complication of this kind.
