Athletic Osteitis Pubis Detected on 18 F-FDG PET/CT.

A 37-year-old male personal trainer presented with debilitating groin pains, fever, and night sweats. Enlarged inguinal lymph nodes were noticed during physical examination, and blood tests showed elevated erythrocyte sedimentation rate and C-reactive protein. 18 F-FDG PET/CT excluded lymphoma and other malignancy but showed intense FDG uptake at the pubic symphysis and cortical erosions of the pubic bones on CT. The patient was diagnosed with osteitis pubis, an inflammatory condition of the pubic symphysis commonly seen in athletes. Treatment with anti-inflammatory drugs was initiated. Within several weeks, pain decreased, and inflammatory markers normalized.
