Irreversible vasculopathy proceeds rapidly in POEMS syndrome

Abstract

A 48-year-old woman with polyneuropathy, organomegaly, endocrinopathy, M-protein, skin change (POEMS) syndrome suddenly presented with numbness of her right upper limb. Magnetic resonance imaging showed multiple acute infarctions in her left cerebrum, and magnetic resonance angiography (MRA) showed multiple intra-cranial vascular lesions, which contrasted with previously normal MRA results obtained eight months prior to the stroke. After completing successful treatment for POEMS syndrome, there were no recurrent stroke episodes. A six-month follow-up scan showed that although the vascular lesions did not progress, they did not improve much either. POEMS syndrome is associated with the rapid extension of large blood vessels-vasculopathy-resulting in nearly irreversible brain lesions.
