title: Postorchiectomy intrascrotal hematoma mimicking local recurrence on 18F-FDG PET/CT: a diagnostic dilemma.
abstract: Intratesticular hematomas usually develop immediately after orchiectomy is done for testicular tumors and may last for 3 to 6 weeks or longer. They may be confused with local recurrence on clinical examination and imaging. We present the (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images of a 30-year-old man who underwent right radical transinguinal orchiectomy for seminoma. PET/CT done 8 weeks after orchiectomy revealed a soft tissue lesion in the right scrotum with increased FDG uptake, suspicious for local recurrence. However, on color Doppler ultrasonography of the scrotum, the mass was confirmed to be a hematoma.
