Abstract
Of 700 neonates examined by computed tomography (CT) in a 4-yr period, 17 had a posterior fossa hemorrhage. Eleven were born at term and 6 were premature. Delivery was traumatic in 12. The hematoma was in the subdural space in 9 and within the cerebellum in 8. The CT diagnosis of extravasated blood in the posterior fossa is easy both in full-term neonates and prematures. The localization of the hematoma may be difficult. In the full-term neonates differentiation between subdural and intracerebellar location is relatively easy. In the premature the cerebellar hematoma frequently has a crescentic shape that resembles a subdural collection. Four patients with a subdural hematoma and 4 with a cerebellar hematoma were operated on. The general prognosis is poor: 7 patients died; of the survivors, only 3 are normal at follow-up.
