A patient with type 2 diabetes, retinopathy, neuropathy, and nephropathy presented with severe right distal thigh pain, which awoke him from sleep. He was diagnosed with musculoskeletal pain and discharged home. Two days later, the severity of pain increased in his right thigh and, subsequently, he developed pain in the proximal lateral aspect of his left thigh, for which he returned to hospital. He had elevated creatine kinase and myoglobin levels. An ultrasound of the right thigh identified a loss of definition of the normal muscular striations and subcutaneous edema. On MRI, the axial STIR image demonstrated extensive T2 hyperintensity in the right vastus medialis and left vastus lateralis, consistent with the diagnosis of diabetic muscle infarction (DMI). This presentation emphasizes the need for a thorough patient history and physical examination, and the importance of directed imaging for the prompt diagnosis of DMI.

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. Magnetic resonance imaging (MRI) of his thighs showed symmetrical bulky muscles with hyperintensities on T2-weighted and short tau inversion recovery (STIR) images, supporting a clinical diagnosis of idiopathic inflammatory myositis (IIM). However, a review of histopathology slides of a muscle biopsy from the right vastus lateralis performed in 2015 showed muscle fibre ischaemic necrosis suggestive of muscle infarction. Thus a diagnosis of recurrent diabetic myonecrosis was made and the patient was treated with bed rest, opioids and aspirin with gradual recovery.
