Pituitary Metastases Discovered by 18F-FDG PET/CT During Other Cancers Monitoring: Are There Any Differences of SUVs Between Benign and Malignant Diseases?

Clin Nucl Med. 2021 Jan;46(1):e44-e46. doi: 10.1097/RLU.0000000000003313.

Abstract

F-FDG PET/CT might discover incidental pituitary lesions. We present the case of a 46-year-old woman with breast cancer metastasis in her pituitary. We analyzed 10,347 FDG PET/CT examinations from a tertiary center, finding 4 cases (0.038%) of pituitary metastatic disease from other cancers. We analyzed the differences between SUVmax in cases of physiological high uptake, primary tumor, and hypophysis metastases from other cancers in our database compared with the literature.
