- Abstract
OBJECTIVE The 2-deoxy-2-[18F] fluoro-D-glucose positron emission tomography (FDG-PET) scan is commonly used in detection and staging of many malignant neoplasms. However, several benign or non-neoplastic conditions avidly accumulate 18F-FDG, causing ambiguity in interpretation of results. It is unknown whether pituitary adenomas uptake 18F-FDG and appear positive in PET imaging. Here, we present 2 cases of benign pituitary adenoma with elevated metabolic activity in 18F-FDG PET scan. METHODS Medical, neurologic, and psychiatric histories; physical examination findings; laboratory work up results; and pathologic and imaging studies were documented. RESULTS The 18F-FDG-PET images revealed foci of marked FDG uptake in pituitary adenomas of 2 patients. CONCLUSION Pituitary micro- and macro-adenomas may present as hypermetabolic foci on 18F-FDG PET scan.
