Paraparesis Secondary to Microscopic Polyangiitis Resistantto Corticosteroids. Report of a Case

Abstract

Microscopic polyangiitis (MPA) is an ANCA-associated vasculitis. Almost half of the patients may present with involvement of the peripheral nervous system such as mononeuropathy or polyneuropathy. The initial treatment is with corticosteroids, and up to 30% are non-responders, where other treatments should be used. Rapidly progressive renal failure and intestinal ischemia are usually high-mortality complications.
