Diabetic myonecrosis: an unusual mimicker of idiopathic inflammatory myositis

Diabetic myonecrosis or diabetic muscle infarction (DMI), is a very rare and under-recognised complication of poorly controlled long-standing diabetes mellitus. We report a case of a 59-year-old male, who had diabetes for ten years. He presented with bilateral thigh pain of insidious onset for three months and difficulty in walking, with a similar episode in his right thigh in 2015. Creatine phosphokinase (CPK) was one and half times the normal upper limit.
