Increased Prostate-Specific Membrane Antigen Uptake in Neurofibromatosis

A 51-year-old man with 30-year neurofibromatosis and 2-month elevated prostate-specific antigen and back pain underwent a 68Ga–prostate-specific membrane antigen (PSMA) PET/CT scan for possible prostate cancer. Prostate-specific membrane antigen PET/CT imaging showed no abnormal uptake of the prostate. However, in addition to PSMA uptake in his left lung, thorax, and right ilium, which was confirmed being a lung squamous cell carcinoma by a lung biopsy, widespread uptake was also observed in his skin fibroma lesions. This case demonstrates that benign neurofibromatosis could have uptake of PSMA.
