Résumé
Pituitary macroadenoma constitutes a frequently misdiagnosed benign tumor. We report herein a case where such macroadenoma, a prolactinoma, was incidentally discovered in a 63-year-old man who had been referred to F-FDG PET and F-FDOPA PET imaging for a pharmacoresistant epilepsy. An increased uptake was documented for both radiotracers within the sellar region, although with a much higher contrast for F-FDOPA than for F-FDG. This case presents an increased uptake documented within a prolactinoma owing to the high contrast and image quality provided by F-FDOPA PET.
