Inclusion Body Myositis: A Late Diagnosis Case Report

Abstract

Inclusion body myositis is a idiopathic inflammatory myopathy characterized by muscle weakness and dysphagia, with muscle biopsy showing inflammation and rimmed vacuoles. We present the case of a patient who was diagnosed with polymyositis but due to lack of response to treatment, a new biopsy revealed inclusion body myositis.
