Result
The postoperative MRimages show the extent of the tumor resection. There was only a small residual tumor remaining in the right cerebellopontine angle which was subsequently removed in a second operation via a right retrosigmoid craniotomy. A slight hypesthesia in the left side of the face and a partial abducens palsy which occurred after the second operation, disappeared completely within the first two months after surgery. The patient now displays no neurological deficits and the MR imaging revealed no evidence of a recurrent tumor.
