BACKGROUND: Schimke immuno-osseous dysplasia is a rare autosomal recessive disease resulting from biallelic SMARCAL1 mutations. It presents in early childhood and is characterized by short stature, nephropathy, and immunodeficiency. Approximately 50% of those affected have neurological complications including migraines, transient ischemic attacks, and strokes.
METHODS: We present a six-year-old boy with Schimke immuno-osseous dysplasia without evidence of atherosclerosis with recurrent episodes of severe headache, fluctuating hemiparesis, and aphasia.
RESULTS: Magnetic resonance imaging and angiography were normal during the initial episode; multiple areas of reversible restricted diffusion with decreased perfusion and arterial stenosis were seen with subsequent attacks.
CONCLUSIONS: This constellation of symptoms and imaging findings is suggestive of reversible cerebral vasoconstriction syndrome, which we propose as a mechanism for the transient ischemic attacks and infarcts seen in some patients with Schimke immuno-osseous dysplasia, as opposed to accelerated atherosclerosis alone. This new insight may provide a basis for novel preventative therapy in this rare disorder.
