A Case of Moyamoya Disease without Transient Ischemic Attacks

ABSTRACT

Moyamoya disease is a cerebrovascular disorder characterized by internal carotid arteries' occlusion or stenosis. Its etiology remains unknown, and it occurs more frequently in Asian countries than western countries. It can occur at any age, and approximately 50% of patients are children. Initial manifestations of moyamoya disease are very different according to age. In general, cerebral ischemic symptoms like transient ischemic attacks (TIA) are the most common manifestation of children. It is a chronic progressive disease and cause recurrent stroke, so early diagnosis and management is very important. We report a case of moyamoya disease without TIA, in a 7 years old female child presenting as unusual symptoms, such as walking difficulty and dysarthria.
