Abstract

Testicular lymphoma is an uncommon testicular tumor that usually presents as a painless mass. It usually shows hypervascularity on color Doppler ultrasound (US) and a mild enhancement on enhanced CT or MRI. We present an unusual case of a testicular lymphoma mimicking a missed testicular torsion in a 67-year-old male patient with right scrotal swelling and intermittent pain for 2 months. Color Doppler US demonstrated the absence of vascularity in the enlarged right testis, and the initial diagnosis was a missed testicular torsion. CT demonstrated a poorly enhancing mass rather than a missed testicular torsion with enhanced small nodular foci at the periphery. The final pathological diagnosis was testicular lymphoma.

고환 림프종은 무통성 종괴를 주소로 내원하는 드문 고환 종양이다. 일반적으로 고환 림프종은 칼라 도플러 초음파에서 고혈관성을 보이며, 컴퓨터단층촬영이나 자기공명영상에서 조영증강을 보인다. 저자들은 우측 고환 종대를 주소로 내원한 67세 환자에서 초음파 검사상 크기가 커진 고환 내 혈류가 보이지 않아 계류염전으로 진단하였으나, 전산화단층촬영에서는 주변부에 일부 조영증강을 보이는 종괴로 관찰되었고, 수술 이후 림프종이 진단된 증례를 경험하여 보고하고자 한다.
