Moyamoya disease is a chronic progressive vascular disease of brain characterized by bilateral stenosis or occlusion of the arteries around the circle of Willis with prominent arterial collateral circulation. We introduce here a patient with Moyamoya who was misdiagnosed. She was a 16-yr-old female from north east of Iran who complained left hemiparesis and was diagnosed Moyamoya disease by bra...

abstract introduction moyamoya is a rare chronic progressive occlusive cerebrovascular disease that its manifestation varies from stroke, progressive learning impairment and transient ischemic attack to headache and seizure. there is no known medical treatment and surgery usually is needed. the incidence of this disease is about 1 person in 10 million people and angiographic picture of this dis...

case presentation we report a 5-year-old boy, who was presented with sudden right hand monoparesis and dysarthria. conclusions the patient was investigated with magnetic resonance angiography and diagnosed as md. introduction moyamoya disease (md) is a disorder caused by blocked arteries at the base of the brain. as the normal blood vessels narrow and become blocked, a person may suffer a strok...

moyamoya disease is a rare vaso-occlusive illness with an unknown etiology characterized by stenosis of the internal carotid arteries with spontaneous development of a collateral vascular network. a 15-month-old girl was referred to the emergency ward of imam reza hospital due to decreased level of consciousness, focal seizures and fever during the previous 24 hours with an impression of enceph...

A 21-year-old woman presented with moyamoya disease manifesting as speech disturbance and right quadrant hemianopsia on October 22, 1994. Magnetic resonance (MR) angiography showed occlusion of the left internal carotid artery (ICA) with the normal right ICA. The diagnosis was "unilateral" moyamoya disease by conventional angiography. Follow-up MR angiography revealed further occlusive changes ...

A 71-year-old woman presented with sudden akinetic mutism. MRI showed an infarction on the anterior portion of the brain. Angiographic studies demonstrated occlusion of both internal carotid arteries at the supraclinoid portion and extensive collaterals (figure), which were suggestive of moyamoya disease.1 Although symptom onset at age 71 is unusual in moyamoya disease, underlying diseases that...

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 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 rare chronic and progressive cerebrovascular disease of the arteries of the circle of Willis that can affect children and adults. It has been associated with multiple diseases, including immunologic, like Graves' disease, diabetes mellitus, and SLE. Hyperlipidemia has been recognized in patients with Moyamoya disease with an incidence of 27-37%. However, no case in pediatr...
