Abstract

There have been many reports of angiographic extravasation since the first description by Jamieson in 1952. Preoperative differential diagnosis between epidural and subdural post-traumatic blood collections is not always possible on the basis of cerebral angiographic signs alone, but many authors considered that extravasation of the contrast medium from a ruptured meningeal vessel is commonly considered as a definitive angiographic sign of epidural hematoma. Some authors feel that an extravasation of contrast medium from rupture of the middle meningeal artery does not necessarily indicate an epidural hematoma since it may also be formed rarely in cases of subdural or intracerebral blood collections. The authors report 6 cases of angiographic extravasation in head injury patient, 3 epidural hematoma, 2 subdural hematoma and one intracerebral hematoma.
