Figure 3. Neurovascular abnormalities associated with MOPDII. Coronal (A), sagittal (B), and transverse (C) section of MR angiogram of the brain shows occlusion of both internal carotid arteries (marked with red arrows) and collateral supply of the anterior territory through the leptomeningeal circulation and branches of the external carotid artery, as well as inverted flow in both ophthalmic arteries. The leptomeningeal collaterals are also supplied by both posterior cerebral arteries; no clear occlusions are visible in the posterior circulation. These changes are related to moyamoya syndrome (stage IV, according to Suzuki’s classification).
