Abstract
We present a patient who experienced sudden onset of orbital headache, visual loss and bitemporal visual field defect. MRI of the optic chiasm suggested a diagnosis of haemorrhage and hence a vascular malformation. Pterional craniotomy revealed an intrachiasmatic haematoma with a cavernous angioma. The malformation was totally excised and vision improved after surgery. The syndrome of chiasmal apoplexy is discussed.Keywords
