We report a patient with calcification of the convexity dura mater and an acute epidural haematoma. CT revealed a calcified layer between the haematoma and brain parenchyma, which mimicked acute bleeding into a calcified chronic subdural haematoma. The appearance of a calcified haematoma does not always mean a “chronic” lesion, and that emergency operation should not be foregone, when there is a history of acute head trauma and progressive impairment of consciousness.
