Intermittent FDG uptake in lipomatous hypertrophy of the interatrial septum on serial PET/CT scans.
We present a unique case of a patient with a clinical history of distal esophageal carcinoma and CT appearance of lipomatous hypertrophy of the interatrial septum who displayed fluorine-18-fluorodeoxyglucose (FDG) uptake in the interatrial septal fat on only the second of 4 serial PET/CT studies. As PET/CT scans are used for the initial staging of esophageal carcinoma, one should not mistake more benign causes of mediastinal uptake for metastasis when observing an intermittent pattern of uptake on a PET/CT scan.
