Increased radiopharmaceutical uptake in the mediastinum and/or hilum on Ga-67 citrate scan in patients with AIDS has been attributed, to date, mostly to infectious etiologies. Because other complications are being reported in these patients, awareness of their presentation in diagnostic imaging is important. Tracheoesophageal fistula can also be accompanied by a focal area of increased uptake in the mediastinum. In this patient, a Ga-67 citrate scan was the first modality of diagnostic imaging to raise suspicion of such a diagnosis.
