Objective Moyamoya vasculopathy associated with skull base tumors has been rarely reported except for partially removed pituitary adenoma and craniopharyngioma. Only a single case of meningioma resulted in vast cerebral infarction. Surgical treatment carries a high risk of damage to the compensatory collateral circulation through leptomeningeal anastomosis leading to a devastating outcome. Case...

Moyamoya disease is characterized by progressive occlusion of the internal carotid artery or its terminal branches, associated with formation of extensive collateral vessels (moyamoya vessels) at the base of the brain. Whether unilateral moyamoya disease, confirmed by typical angiographic evidence of moyamoya disease unilaterally and normal or equivocal findings contralaterally, is an early for...

Five cases of paediatric stroke are reported. Two patients presented with idiopathic stroke, another following vertebral artery dissection, one secondary to Moyamoya disease, and one patient with the syndrome of mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes. The presentation, investigation, and management of paediatric stroke are discussed.

We describe a boy who presented at the age of 7 years with short stature due to hypopituitarism. Six months after starting appropriate hormone replacement treatment at the age of 8 he suffered his first generalised convulsion. Further neuroradiological investigation led to the diagnosis of moyamoya syndrome.

BACKGROUND AND PURPOSE Moyamoya disease is a progressive cerebrovascular occlusive disease affecting primarily children. The etiology remains unknown. We examined the chemotactic and proliferative activities of inflammatory cell products from arterial smooth muscle cells (SMCs) derived from moyamoya patients and compared them with those from control subjects. METHODS We used 12 SMC strains fr...

Moyamoya disease is a progressive cerebrovascular occlusive disease that primarily affects children. The cause is unknown. We examined the production of prostanoids and the expression of cyclooxygenase-2 (COX-2) in cultured arterial smooth muscle cells (SMCs) derived from patients with moyamoya disease. Twelve moyamoya and 8 control cell strains were examined. The steady-state levels of prostan...

BACKGROUND AND PURPOSE Cerebral hyperperfusion syndrome is a potential complication of superficial temporal artery-MCA anastomosis for Moyamoya disease. In this study, we evaluated whether TOF-MRA could assess cerebral hyperperfusion syndrome after superficial temporal artery-MCA anastomosis for this disease. MATERIALS AND METHODS This retrospective study included patients with Moyamoya disea...

OBJECTIVE Moyamoya angiopathy (MMA) affects the distal internal carotid artery and is designated as moyamoya disease (MMD) when predisposing conditions are absent, or syndrome (MMS) it occurs secondary to other causes. The authors aimed investigate reason for this anatomical site predilection of MMA. There compelling evidence suggest that MMA a phenomenon due stereotyped mechanobiological proce...
