title: Moyamoya Syndrome Associated with Henoch-Schönlein Purpura.
abstract: Some reports have shown the association between Moyamoya syndrome and autoimmune diseases. Herewith, we present a 3.5 yr old girl with Henoch- Schönleinpurpura (HSP) who was treated with steroids because of sever colicky abdominal pain. However, central nervous system manifestations such as headache, ataxia and vision impairment developed during 6 months of her outpatient follow-up. More evaluation using MRA revealed intracranial stenosis of internal carotid artery and arterial collaterals that were in favor of Moyamoya syndrome. To our knowledge, this is the first report of Moyamoya syndrome following henoch-schönleinpurpura.
