Extravasation of contrast-enhanced blood into the subarachnoid space during computed tomography.
Four cases are described in which there was extravasation of contrast medium into the subarachnoid space at the time of enhanced CT. Three were being investigated for a previous subarachnoid haemorrhage which was due to an aneurysm in two and an angioma in one. The other patient had suffered a severe head injury.
