FDG PET/CT in a Case of Bilateral Tuberculous Epididymo-orchitis.

Isolated genital tuberculosis is rare. We present a case of bilateral tuberculous epididymo-orchitis showing high FDG uptake on FDG PET/CT. In addition, the patient had a prostatic FDG-avid lesion, consistent with tuberculous prostatitis. This case indicates tuberculous epididymo-orchitis, especially in tuberculosis-endemic regions, should be considered as a differential diagnosis in patients with hypermetabolic epididymal or testicular lesions, including benign and malignant tumors, bacterial epididymo-orchitis, abscess, idiopathic granulomatous orchitis, and sarcoidosis.
