Posterior cranial fossa venous extradural haematoma: an uncommon form of intracranial injury

Abstract

Extradural haematomas are commonly associated with direct trauma to the temporal bones of the cranium resulting in damage to the middle meningeal artery or its branches. A case is presented of an occipital skull fracture with venous sinus bleeding that resulted in a posterior cranial fossa extradural haematoma. Bleeding in this area, if unrecognised, may lead rapidly to respiratory arrest secondary to brainstem compression. The presence of significant trauma to the occiput should alert the attending clinician to the possibility of this uncommon but potentially fatal condition.
