Diabetic myonecrosis in a cystic fibrosis patient

Abstract

Cystic fibrosis-related diabetes is an increasingly common co-morbidity in cystic fibrosis (CF) patients with scarce data on end-stage complications in the CF population. We report the case of a 32 year old with poorly controlled diabetes presenting with subacute leg pain and focal quadriceps tenderness. The patient was found to have diabetic myonecrosis through careful neuromuscular testing and imaging after an extensive workup. This first reported case of diabetic myonecrosis in CF 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.
