Middle Cerebral Artery Territory Infarction Caused by Giant Middle Cerebral Artery Dissecting Aneurysm

ABSTRACT

Dissecting aneurysm of the intracranial arteries is a rare cause of stroke. This condition may induce both ischemic stroke and hemorrhagic stroke by occlusion of the parent artery via direct distortion and stretching, compression secondary to growth of the aneurism, and distal embolization of any intra-aneurysmal thrombi. A patient with an infarction in the right middle cerebral artery territory and a mass lesion located in the right basal ganglia and temporal lobe was examined in this study. The consequent workup suggested that the mass lesion was a huge dissecting aneurysm that had resulted in a cerebral infarction.
