Abstract:
Granulomatous Orchitis secondary to lymphatic filiarisis is a rare diagnosis within the United States. We report a case of a 22yo Male from Sri Lanka, with a new onset scrotal swelling and palpable right testicular mass. Ultrasound identified a 1 cm right testicular mass with signs of tunica albuginea invasion. A right inguinal radical orchiectomy was performed and pathology showed Filarial orchitis. This report describes the detailed history, physical exam, and diagnostic workup and treatment options for a rare entity for acute scrotal pathology.
