Extradural hemorrhage in the newborn as a result of birth trauma.

During the past 18 years, 134 autopsies of intracranial hemorrhages were performed in the Department of Pathology, and 2 cases of extradural hemorrhages were discovered (2.2%). 5 cases of extradural hemorrhage (2 of our own treated surgically and 3 untreated found at autopsy) are described in detail. 1 of the 2 cases treated surgically responded favorably to surgical treatment. The mechanism of hemorrhage into extradural spaces is investigated and reconsidered following review of the literature. The necessity for right reflux brachial angiography is emphasized for early diagnosis of extradural hemorrhage.
