A 72-year-old man who underwent a PET-CT for work-up of a lung nodule. There was a left adrenal nodule (arrow), which demonstrated enhancement post contrast, measuring 112 HU (A). This enhancement level has been described in pheochromocytomas (19). This also showed uptake on 18F-FDG PET (B), and was confirmed as a pheochromocytoma on resection. PET, positron emission tomography; CT, computed tomography.
