PRADA, Leidy Paola et al. Multifocal myopathy in a patient with polyarteritis nodosa; usefulness of magnetic nuclear resonance as a diagnostic test. Rev.Colomb.Reumatol. [online]. 2019, vol.26, n.1, pp.63-67. ISSN 0121-8123.

Polyarteritis nodosa is part of the primary systemic vasculitis that specifically compromises vessels of medium caliber, and can affect virtually any organ. The diagnosis of this disease is based on clinical criteria, such as pain and weakness in the lower limbs, as well as laboratory results and the histology report that shows necrotizing, segmental and focal inflammation of the vessels involved. The case is presented of a 42 year-old woman with a previous diagnosis of polyarteritis nodosa, who, 12 years later, presented with an episode of activation of the disease associated with venous thrombosis and multifocal myopathy in the lower limbs. This is a rare presentation that should be suspected in this type of patients.
