An unusual orbital localization of wegener granulomatosis detected by 18F-FDG PET/CT

Clin Nucl Med. 2014 Aug;39(8):711-2. doi: 10.1097/RLU.0b013e31829b9e82.


We report a case of a 61-year-old male patient affected by Wegener granulomatosis and left exophthalmos who underwent F-FDG PET/CT during follow-up for rectal cancer. The study was negative for secondary lesions but revealed high uptake at the left orbital mass consistent with Wegener granulomatosis.
