A 28-year-old woman with Moyamoya disease. A, Unenhanced CT scan demonstrates pericallosal hematoma (arrow) with extension of hemorrhage into the lateral ventricle. B, Volume-rendered MDCTA image with bone subtraction, anteroposterior projection, demonstrates symmetric occlusion of the bilateral proximal MCAs (arrows). MDCTA image fails to show collateral vessels. C and D, Corresponding DSA images of the right (C) and left (D) carotid arteries, anteroposterior projection, confirm occlusion of the bilateral proximal MCAs (arrows). In addition, reconstitution of the distal MCAs via fine collateral vessels is also noted.
