  • Abstract
  • Look Inside

Although the cases in which the extravasation-like shadow was demonstrated on angiograms of the traumatic epidural hematoma are comparatively rare, they have been reported by ;Jamieson (1952), Lofst-rom et al. (1955), Vaughan (1959), Huber (1962), Leslie (1962), Cronqvist (1963), Wortzman (1963) and others.

In our country, Hirai et al. (1965) have made a report about it. In the last about six years from 1963 to April, 1968, 50 cases of traumatic epidural hematoma were admitted to our clinic. In 34 out of the whole cases the extravasation-like shadow was followed-up on their cerebral angiograms.

In 8 of there 34 cases (21. 6%) the extravasation-like shadow was evident, and in 5 (13. 5%) a finding highly suggestive of it was obtained.

Huber stated that there exists some relation bet-ween the interval from injury to cerebral angio-graphy and the appearance of the extravasation-like shadow and that the shorter the interval, the more it appears.

In 8 cases in which the extravasation-like shadow was demonstrated by us, however, the interval from injury to cerebral angiography ranged from the shortest 4 hrs to the longest 8 days, in 5 of which it was within 27 hrs. Moreover, it was found that this shadow appears in most cases at the arterial phase of cerebral angiography, and that it does so mostly near the crossing of a branch of the middle meningeal artery with a fracture line. Since the present shadow tends to appear frequently in cases of the epidural hematoma, it proves to be helpful in differentiating it from the acute subdural hema-toma.
