LIZARAZO, Jairo; NINO, Freddy; ALVARADO, Hugo e CASTRO, Noé. Moyamoya syndrome and Graves' disease in a young woman. Acta Med Colomb [online]. 2013, vol.38, n.4, pp.262-267. ISSN 0120-2448.
Abstract Introduction: the disease and moyamoya syndrome are cerebrovascular entities characterized by stenosis or occlusion of the terminal portion of the internal carotid artery and the proximal portion of the middle and anterior cerebral arteries, accompanied by the formation of collateral vessels in the form of network. Graves' disease is an autoimmune thyroiditis of unknown origin and is the most common cause of hyperthyroidism. The association of these two diseases is rare. Case report: 27 year-old woman hospitalized for a stroke and hyperthyroidism due to Graves' disease. Diagnostic imaging identified a large right temporoparietal infarct in the territory of the middle cerebral artery. Additionally, stenosis of the supraclinoid portion of the right internal carotid artery and the proximal portion of the anterior and middle right cerebral arteries without the presence of collateral vessels, was evidenced. Initially, she was treated with antithyroid drugs and steroids. Two treatments with radioactive iodine to control hyperthyroidism were needed. The brain injury left sequelae of left motor and sensory deficits and symptomatic focal epilepsy, controlled by medication. She is currently receiving thyroid substitution therapy and anticonvulsant therapy. Angiographic follow-up showed increased vessel stenosis of the cerebral affected vessels without evidence of new brain lesions. Conclusions: patients with hyperthyroidism secondary to Graves' disease and acute focal neurological manifestations should be investigated for possible moyamoya syndrome.
