ABSTRACT |
Glioblastomas rarely occur in the posterior fossa. The authors present clinical and pathological findings in a 59-year-old female patient with a glioblastoma growing primarily in the cerebello-pontine angle. The patient presented with a 1-month history of diplopia. Neurological examination revealed right-sided trigeminal and abducens nerve paresis. Cerebral magnetic resonance imaging showed a well-enhancing mass at cerebello-pontine angle. Following near total removal via petrosal approach, the pathological examination revealed a glioblastoma. To the authors knowledge, this represents the first case of glioblastoma arising at cerebello-pontine angle, probably originating from the most proximal part of abducens nerve. |
