Mimicking aneurysm in a patient with chronic occlusion of the left middle cerebral artery.

Abstract

The chronic occlusion of intracranial arteries generally has no or mild clinical symptoms, and the clinical symptoms of acute cerebral artery occlusion are mostly manifested as severe cerebral infarction symptoms, which often make early diagnosis difficult, thus losing the best treatment opportunity. Once cerebral infarction occurs, the consequences are difficult to recover. This is also an important reason for the high misdiagnosis rate and mortality of this disease. In this paper, the characteristics of the disease were analyzed to provide clinical reference.
