From: Cerebral large artery stenosis and occlusion in POEMS syndrome
Brain magnetic resonance angiography (MRA) of a patient with Castleman disease variant of POEMS syndrome. Brain MRA (A, B) of a 16-year-old man revealed stenosis (Grade 1) of the proximal portion of the bilateral anterior cerebral arteries (ACAs) and middle cerebral arteries (MCAs), and the terminal portion of the internal carotid arteries (ICAs). Diagnosis was Castleman disease variant of POEMS syndrome, and bortezomib and dexamethasone therapy was started. Although the bilateral ACAs, MCAs, and ICAs stenosis remained, the flow signal of the cerebral arteries was thickened overall on follow-up MRA 22 months after the initial MRA (C, D)
