Multifocal giant cell glioblastoma: case report.

Glioblastoma multiforme (GM) of the cerebellum is a rare tumour. A variant of GM, a multifocal giant cell glioblastoma, initially presenting in the cerebellum, has not previously been reported. A giant cell glioblastoma occurring in a 46-year-old man who presented initially with a cerebellar tumour is described. One month after excision of the tumour, the patient had a grand mal seizure. Computed tomography (CT) showed a low-density lesion in the left temporal lobe. Four months later he developed dysphasia and right-sided hemiparesis. Repeat CT scan revealed a large temporal lobe tumour which was excised, and histologically found to be a giant-cell glioblastoma with histopathological similarities to the original cerebellar tumour. The clinical course, computed tomographic and pathological features of this tumour are described and discussed.
