Moyamoya disease in a Hispanic child: a case report.

Background: Moyamoya disease was initially described by Suzuki and Takaku in 1963 as a radiographic phenomenon relating to the tiny collateral vessels characteristic of the disease that resemble a cloud or puff of smoke. The disease is rare and initially it was believed that the disease was confined to the Japanese population. It consists of occlusive vascular disease at the Circle of Willis with a tendency toward multiple ischemic neurological events and small strokes.
