Pneumonia and Poorly Controlled Diabetes

      Case Presentation

      A 47-year-old man with poorly controlled diabetes mellitus (glycosylated hemoglobin 12%) presented to the ED with a 1-week history of fevers, productive cough, and dyspnea. The patient was febrile and hypoxemic on presentation; laboratory testing was remarkable for hyperglycemia and ketoacidosis. The initial chest CT scan showed right lower lobe consolidation and ground-glass opacities (Fig 1A). He was admitted to the ICU and administered IV antibiotics (cefepime and vancomycin) for the treatment of community-acquired bacterial pneumonia.
