We report the case of a 32-year-old with poorly controlled diabetes presenting with sub-acute leg pain and focal quadriceps tenderness. Neuromuscular testing and extensive workup revealed diabetic myonecrosis. To our knowledge, this is the first reported case of diabetic myonecrosis in a patient with CF, and highlights the need for pulmonary physicians to recognize this diabetic complication in CF patients, which is associated with a poor long-term prognosis and existing microvascular complications.
