Microscopic Polyangiitis with Spinal Cord Involvement: A Case Report and Review of the Literature.

Background: Microscopic polyangiitis (MPA) is an ANCA-associated vasculitis (AAV; ANCA denotes antineutrophil cytoplasmic antibody) that causes necrotizing inflammation of small blood vessels. Renal and pulmonary manifestations are common whereas central nervous system (CNS) involvement, and in particular spinal disease, is rare.

Methods: We reviewed a case of MPA presenting with spinal intradural hemorrhage and intracerebral hemorrhage.
