Posterior fossa subdural hemorrhage in the newborn as a result of birth trauma.

During the past 19 years, 229 autopsies of intracranial hemmorrhages were performed at the Department of Pathology, and 23 cases of posterior fossa subdural hemorrhages were discovered (10.0%). 25 cases of posterior fossa subdural hemorrhages (2 of our own treated surgically and 23 untreated found at autopsy) are described in detail. 2 cases treated surgically responded favorably to surgical treatment. The mechanism of hemorrhage into posterior fossa subdural spaces is investigated and reconsidered following a review of the literature. The necessity for CT is emphasized for early diagnosis of posterior fossa subdural hemorrhage.
