This 63 year old female admitted with an 8 month history of deterioration in eyesight, associated with headache and some aphasia over recent months. Examination revealed dysphasia, and a gross right homonomous hemianopia. At operation a tumour was removed from the left parieto- occipital lobe. It appears to be arising from the tentorium.
The specimen is of a lobulated tumour 5.5 cm in diameter and bisected to show external cut surfaces. The tumour is greyish in colour and is covered by a white capsule beneath which several small blood vessels may be seen. The cut surface presents a faintly whorled appearance and several small blood vessels are visible. Histologically, the tumour was a meningioma.
