| Abstract |
|
The confirmatory diagnosis of Moyamoya disease has been obtained by invasive angiographic examination. We report the results of MRI and transcranial doppler sonography of three cases ol Moyamoya disease, which ws disgnosed by clinical and angiography. We think that the diagnosis of Moyamoya disease can be made by noninvasive MRI and transcranial doppler sonography without conventional invasive angiography. 9401014 120 12 1 125

These dissections are usually found extracranially or in a combination of intracranial and extracranial location. Pure intracrainl involvement is uncommon. Particularly in oriental country. This vascular anomaly is one of the important causes of posterior circulation stroke in young and middle-aged adults. Lf manifested as brainstem, ischernia, the usual symptoms and signs are typically neck or occipital pain followed later by particular features of the lateral medullary syndrome. Etiology remains obscure in most cases of spontaneous dissection and management is still controversial. We present three cases of dissecting aneurysm of the intracranial portion of unilateral vertebral artery. The two patients manifested as lateral medullary syndrome with sudden neck pain and digital substracted angiogram revealed proximal narrowed segments and distal fusiform dilatation of the unilateral vertebral arter.,v. The other patient manifested as subarachnoid hemmorrhage and angiographically dilatation at the junction of vertebral artery and posterior inferior cerebellar artery was noted. In operative field, two cases were confirmed as dissecting aneurysm. |
