Abstract
Extradural Haematomas are commonly associated with direct trauma to bones of the cranium resulting in damage to the middle meningeal artery or its branches. The condition is present in 1-3% of the head injuries. A case of super acute extradural posterior cranial fossa Haematoma with a rare computed tomographic (CT) presentation is reported. The patient developed a nearly fatal posterior fossa hematoma appearing on initial CT as a hypo dense opacity which gave a confusing picture. The characteristic image is a well localized, hyper dense, extra cerebral biconvex lesion.

Key Words: acute extradural hematoma, continuous monitoring, posterior cranial fossa
