Abstract

Moyamoya disease is a chronic and unusual cerebrovascular disorder characterized by progressive stenosis and occlusion of the distal portions of internal carotid arteries and its main branches within the circle of Willis. Posterior circulation (vertebral and basilar arteries) may also be affected; however, this presentation is uncommon. As well as stenosis of the terminal portion of intracranial arteries, it is seen the development of a network of collateral vessels abnormally dilated at the base of the brain with an aspect of a “puff of smoke,” whose term in Japanese is described as “moyamoya.” The present study aims to report two consecutive cases of patients who presented to our service with different clinical manifestations. Further investigation with digital subtraction angiography showed a moyamoya pattern.

Resumo

A doença de moyamoya (DMM) é uma desordem cerebrovascular crônica de rara incidência, caracterizada pela estenose progressiva das porções terminais das artérias carótidas internas, associada à proliferação de vasos colaterais anormalmente dilata dos na base do crânio, cujo aspecto se assemelha a uma “fumaça,” definido pelo termo em japonês “moyamoya.” A circulação posterior (artérias vertebrais e artéria basilar) também pode ser acometida, porém de forma menos frequente. A apresentação clínica é variada. O presente estudo objetiva relatar dois casos de pacientes que apresentaram diagnóstico angiográfico compatível com a DMM e manifestações clínicas distintas.
