      Sixteen patients with Moyamoya were studied by computed tomography (CT). In one patient, CT was normal. Cardinal findings in the noncontrast CT in the remaining 15 patients weis cortical atrophy, varying degrees of ventricular dilatation and intracerebral lucent areas. After contrast enhancement, no significant increase in the attenuation values was observed in the intracerebral lucent areas. In seven patients, a slight increase in density was noted in the basal ganglia; however, the increase in density was unexpectedly slight when the dense vascular networks opacified by angiographics were considered.
