Dural arteriovenous malformation with false aneurysm and exophthalmos. A successfully treated case

A case of dural arteriovenous malformation with giant non-traumatic false aneurysm in the left middle fossa is reported. A 10-year-old female patient was admitted to our hospital with pulsating exophthalmos of the left eye, which was successfully treated by ligation of the main feeder and finally by the radical excision of the dural AVM and false aneurysm. False aneurysm of non-traumatic origin is so rare that only two cases were detected in the literature (Reina et al., Sakaki et al.), and no previous case of false aneurysm complicated by dural AVM seems to have been reported.
