Abstract:
Testicular tuberculosis (TB-T) is an uncommon cause of testicular masses or chronic orchiepididymitis that can mimic neoplasia. We present the case of a man in his sixth decade of life with a history of respiratory symptoms who presented with a painless bilateral testicular mass of two months' duration. Chest and abdominal computed tomography (CT) and pelvic magnetic resonance imaging (MRI) revealed findings consistent with pulmonary tuberculosis (TB), abscessed orchiepididymitis, and seminal vesiculitis. Sputum culture and polymerase chain reaction (PCR) of testicular secretions were positive for Mycobacterium tuberculosis (MT) associated with systemic TB. This case report adds to the current evidence on the differential diagnosis of testicular masses in the context of MT infection.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
