title: Intracranial arterial dissection.
abstract: We review the angiographic and CT findings, precipitating factors and clinical features in nine patients with ten intracranial arterial dissections. The internal carotid artery was involved in five cases, the vertebral artery in four and the posterior inferior cerebellar artery in one. Angiography revealed irregular stenosis in four cases, irregular stenosis and a pseudoaneurysm in two, irregular stenosis and irregular dilatation in one, arterial occlusion in two and a pseudoaneurysm in one. CT demonstrated an infarct in four cases, a dense middle cerebral artery in two and subarachnoid haemorrhage in one. A possible precipitating factor was identified in five cases. Six patients recovered well, while three had persisting neurological deficits.
