Abstract:
Polyarteritis nodosa (PAN) is a multi systemic disease, occasionally described as limited forms of the disease. Localized form of PAN is usually associated with better prognosis. We describe unusual two cases of patients who has suffered from sudden onset of low extremity pain by localized forms of polyarteritis nodosa. Magnetic resonance imaging of the lower legs showed abnormal signal intensity of the suspected muscle. Acute necrotizing arteritis with myopathy has been revealed by muscle biopsy. The symptom of the patient has been improved soon after corticosteroid administration. Muscle biopsy of symptomatic muscles or MRI-directed biopsies can be useful to diagnose this case as PAN with localized myopathies.
