Abstract It is well known that moyamoya disease sometimes is accompanied by cerebral aneurysm; however, no case of moyamoya disease with arteriovenous malformation has previously been published. We report such a case. A 33-year-old man suffered from transient left motor weakness and visual disturbance. Plain computed tomography (CT) showed a low density area in the left parietooccipital cortex. Enhanced CT revealed a ribbon-shaped enhanced area in the right temporooccipital cortex and a spotty enhanced area in the right frontal subcortex. Cerebral angiography revealed moyamoya disease. On the basis of Suzuki's angiographic classification, the patient was diagnosed as Stage III. Right carotid angiography revealed an arteriovenous malformation fed by basal moyamoya vessels and draining to the vein of Trolard and the sylvian vein of the right frontal lobe. This arteriovenous malformation consisted of feeders, the nidus, and drainers. Trolard's vein, which was one of the draining veins of the arteriovenous malformation, flowed to the moyamoya vessels of the right parietal vault.

Internal Carotid Arteries

Moyamoya disease is characterized by a chronic stenoocclusive vasculopathy affecting the terminal internal carotid arteries. The clinical presentation and outcome of moyamoya disease remain varied based on angiographic studies alone, and much work has been done to study cerebral hemodynamics in this group of patients. The ability to measure cerebral blood flow (CBF) accurately continues to improve with time, and with it a better understanding of the pathophysiological mechanisms in patients with moyamoya disease. The main imaging techniques used to evaluate cerebral hemodynamics include PET, SPECT, xenon-enhanced CT, dynamic perfusion CT, MR imaging with dynamic susceptibility contrast and with arterial spin labeling, and Doppler ultrasonography. More invasive techniques include intraoperative ultrasonography. The authors review the current knowledge of CBF in this group of patients and the role each main quantitative method has played in evaluating them, both in the disease state and after surgical intervention.
