Dense artery sign of the middle cerebral artery on non-enhanced computed tomography is recognized as an early sign of ensuing major cerebral infarction and is usually a consequence of thrombosis or embolism of an ischaemic stroke. A case is described resulting from trauma that correlated with angiographic and Doppler ultrasound findings and the significance of this sign in this case is discussed.
