Computed Tomography in Moyamoya Disease

Cerebral infarction due to moyamoya disease in young adults.

“…CT studies of patients with moyamoya disease and ischemic complications also demonstrated multiple and bilateral cerebral infarctions. 34 - 35 Presence of multiple bilateral cerebral infarctions in hemodynamically compromised regions in a young adult should alert the physician to the possibility of moyamoya disease.…”

Intelligence in children with moyamoya disease: evaluation after surgical treatments with special reference to changes in cerebral blood flow.

“…16 Maki et al 2 reported on the clinical results in 24 children with onset below the age of 13, and an average follow-up period of 5 years and 9 months. Of their 24 children, 7 had a good prognosis, of which 5 had no symptoms and 2 had slight weakness.…”

The contribution of imaging in diagnosis, preoperative assessment, and follow-up of moyamoya disease

“…1A), common CT findings in patients with moyamoya disease are those of ischemic cortical stroke. In a series of 18 moyamoya patients, 80 14 presented with mono-or bilateral cortical or subcortical low-density lesions, consistent with en- The CT angiography studies of the brain show tight stenosis of the supraclinoid ICAs (black arrows in C) and multiple tiny collateral vessels replacing the M 1 segments of the MCAs bilaterally (white arrows in B and C). D: Cerebral angiogram in lateral projection of the left ECA shows collateral flow from the MMA (arrow) opacifying vessels in the posterior MCA territory (arrowheads).…”

“…43,77,80 Catheter angiography still represents the gold standard for moyamoya diagnosis. Three features usually characterize the vascular picture on angiography studies: stenosis of the supraclinoid distal ICA; the development of dilated striate arteries (moyamoya collateral vessels with a characteristic blush); and sparing of the posterior fossa vessels (Fig.…”
