Supratentorial intracerebral hemorrhage following posterior fossa surgery

Five cases of supratentorial intracerebral hemorrhage following posterior fossa surgery are reported. Possible etiologies are discussed, but in only one case can a definite etiology (hypertension) be found. The differential diagnosis of declining level of consciousness after posterior fossa surgery must include supratentorial intracerebral hemorrhage, and computerized tomography seems to be the diagnostic method of choice.
