From: Cerebral large artery stenosis and occlusion in POEMS syndrome
Computed tomography angiography (CTA), computed tomography (CT), and pathological finding of the autopsy case. CTA at 6.8 years after diagnosis of POEMS syndrome (A), when the patient presented with recurrent left hemiplegia, showed stenosis (Grade 1) in the bilateral middle cerebral arteries (MCAs) (black arrows) and left carotid arteries and anterior cerebral arteries. CT 9 weeks later (B) revealed extensive infarction in the bilateral MCA territory. Autopsy demonstrated MCA was occluded and Elastica van Gieson (EVG) staining showed disruption and duplication of the internal elastic lamina (black arrowheads) (C). Scale bars: (C) 200 μm
