Two women were referred for an 18 F-PSMA-1007 PET/CT in follow-up of an adenoid cystic tumor of the subglottic region and the bronchus, respectively. Only limited tracer uptake was seen in the region of local recurrence and in the region of known metastases. Unexpectedly, an incidental finding consisting of a high tracer uptake at a corpus luteum in the ovary was found in both women.

A 27-year-old man was called to receive a kidney transplant. The preoperative CT of the chest showed multiple osteolytic lesions, as well as a hypodense structure posterior in the right thyroid lobe. Blood analysis showed elevated parathyroid hormone, phosphorus, and alkaline phosphatase levels, with normal calcium and 25-OH-vitamin D. 18F-FDG PET/CT demonstrated generalized elevated FDG uptake in the bone (due to hyperparathyroidism), as well as multiple hypermetabolic focal lesions spread throughout the bone (fitting brown tumors). The nodule posterior of the right thyroid lobe showed an intense FDG uptake as well, suggestive of a parathyroid adenoma/hyperplasia. Histopathology confirmed the diagnosis.
