Context: Moyamoya disease or chronic occlusive cerebrovascular disease is characterized by proximal occlusion of the internal carotid artery and its branches bilaterally, generating an angiographic “smoke” pattern (moyamoya, from Japanese “something hazy”) and by diverse ischemic manifestations. Case report: The sample consists of three female patients, aged between 13 and 46 years, followed in our service due to the diagnosis of Moyamoya Disease. Among the clinical manifestations presented, ischemic cerebrovascular events with neurological deficit predominated, and one of the patients presented two episodes compatible with stroke and one episode compatible with transient ischemic accident. The youngest patient presented with a choreic picture initially interpreted as Sydenham’s chorea. Although the gold standard for the diagnosis of chronic occlusive cerebrovascular disease is cerebral arterial angiography, it was possible to observe a pattern compatible with the disease in other modalities of examination, such as cerebral arterial angiotomography and cerebral arterial angioresonance. From the therapeutic point of view, one of the patients underwent surgical intervention (encephaloduromyosinangiosis), with improvement of symptoms after treatment. Conclusions: In this paper, we emphasize the importance of complementary imaging tests in the evaluation of patients with cerebrovascular syndromes and the diversity of clinical presentation of Moyamoya disease. |
