Abstract
A 25-year-old male sustained head injury and was admitted to our hospital about two hours later. CT scan on admission showed traumatic intracerebral hematoma in the right basal ganglia without mass effect and its ventricular rupture was also found. Skull plain film showed no fracture. Follow-up CT scan about 19 hours after injury showed enlargement of the hematoma with minimal perifocal edema. Right carotid angiogram performed just after the initial CT scan showed extravasation of the contrast medium. Clinically he was comatose and decerebrated. He died about 21 hours after head injury.
It is a matter of common knowledge that we can sometimes find extravasation of the contrast medium on cerebral angiogram, but extravasation of the contrast medium into the traumatic intracerebral hematoma is relatively rare and minimal.
In this case, intracerebral extravasation of the contrast medium was considered to be the radiological feature of active hemorrhage, because the enlargement of hematoma on CT scan performed both just before and after the cerebral angiography was recognized
