Imaging findings of reversible cerebral vasoconstriction syndrome. Multifocal vasoconstriction demonstrated by magnetic resonance angiography (MRA) (A) and catheter angiography (B), involving the anterior, middle, and posterior cerebral arteries. Follow-up MRA (C) revealed significant interval resolution of the previous lesions. Axial fluid attenuated inversion recovery (FLAIR) imaging revealed linear hyperintensity lesions in the sulci of the bilateral frontal lobes (D).
