OBJECTIVES To report a rare case of moyamoya syndrome with primary antiphospholipid syndrome (APS). CLINICAL PRESENTATION AND INTERVENTION A 41-year-old woman was admitted with sudden onset of left-sided hemiparesis. Magnetic resonance imaging and magnetic resonance angiography of the brain showed characteristic features of moyamoya vessels. Laboratory investigations revealed raised levels of...

Moyamoya vascular pattern and dural arteriovenous fistula (dAVF) are rare vascular abnormalities and both can be secondary to head trauma. The role of dural angiogenesis in the pathophysiology of vascular malformation is rather unclear. We report a unique case of moyamoya vasculopathy simultaneously associated with dAVF after heavy head trauma. It seems that both moyamoya syndrome and dAVFs are...

Moyamoya is an intriguing and controrersial syndrome. This patient study senes to align the patbophysiology of intracranial hemorrhage in moyamoya with the cerebral rascular disease seen with hypertension, or aging. The historical eridence Unking lipohyalinosis and microaneurysms to cerebral hemorrhage is reviewed, the pathogenesis of this angiopathy Is discussed, and explanations considered fo...

We report on a 13-year-old female with systemic lupus erythematosus (SLE) who exhibited symptoms of severe migraine and familial moyamoya disease. Cerebral magnetic resonance angiography (MRA) showed stenosis and occlusion of the bilateral internal carotid arteries associated with the development of collateral circulation (moyamoya vessels). In a child, as in this case, headaches with cerebral ...

BACKGROUND Essential thrombocythemia (ET) is a chronic myeloproliferative disorder with increased frequency of thrombotic events, including transient ischemic attacks (TIAs) and stroke. Moyamoya syndrome is a rare cerebrovascular disease characterized by progressive occlusion of intracerebral arteries with a typical "puff of smoke" angiographic pattern. We report the development of moyamoya syn...

Neurofibromatosis type 1 (NF1) is the most prevalent autosomal dominant genetic disorder among humans. NF1 vasculopathy is a significant but underrecognized complication of the disease, affecting both arterial and venous blood vessels of all sizes. Moyamoya syndrome is a cerebral vasculopathy that is only rarely observed in association with NF1, particularly in the pediatric age range. Herein, ...

Moyamoya syndrome is the secondary form of intracranial arterial occlusive diseases that produces collateral vessels from the base of brain. We report a case of Moyamoya syndrome developing in association with Graves thyrotoxicosis; as a result of its rapid progression and severe global ischemia, it was ultimately fatal. Because of the rarity of this association, we reviewed the literature in a...

AGS: Aicardi-Goutieres syndrome CTCL: cutaneous T-cell lymphoma SAMHD1: SAM domain and HD domaincontaining protein 1 SAMS: stroke, aneurysm, moyamoya, and stenosis SLE: systemic lupus erythematosus INTRODUCTION Mutations in the SAMHD1 (SAM domain and HD domainecontaining protein 1) gene are implicated in SAMS (stroke, aneurysm, moyamoya, and stenosis) association, also described as AicardiGouti...

Pediatric and inherited neurovascular syndromes have diverse presentations and treatments. Although many of these diseases are uncommon, they must be included in the differential diagnosis for children with strokes or hemorrhages. In neurosurgical practice, familial cavernous malformations, hereditary hemorrhagic telangiectasia (HHT), and moyamoya are the most frequently encountered of these di...

Moyamoya is an intriguing and controversial syndrome. This patient study serves to align the pathophysiology of intracranial hemorrhage in moyamoya with the cerebral vascular disease seen with hypertension, or aging. The historical evidence linking lipohyalinosis and microaneurysms to cerebral hemorrhage is reviewed, the pathogenesis of this angiopathy is discussed, and explanations considered ...
