Moyamoya is a rare cerebrovascular disorder marked by chronic, gradual blockage of the circle of Willis arteries, leading to characteristic collateral vessels, specifically cerebral angiography. The disease can develop in children and adults, although there are different clinical characteristics. Moyamoya disease occurs mainly in Japanese people but has been reported in all races of varying age distributions and clinical features. As a reason, Moyamoya disease has been under-recognized as a cause of hemorrhagic and ischemic strokes in Western nations. There is no proven solution at this time, and there is debate over current care methods. The authors identify a case of a 40-year-old male with a small subcutaneous nevus-like mass in his left orbit who was diagnosed with Moyamoya disease.
