Intracerebral venous angiomas as a cause of exophthalmos

Three cases of an infrequent cerebral vascular malformation, venous angioma, are reported. The first 2 of these cases, with the lesion in a supratentorial location, exhibited exophthalmos as a presenting symptom, together with palpebral or intraobital angiomatous formations, and also impairment of visual function. The first patient was operated upon and the "venous angioma" could be confirmed histologically. An angiographic follow-up of the same patient at an 18 year interval was also possible. The diagnostic work-up to be performed in cases of exophthalmos is discussed and the need for angiography is stressed.
