Abstract

Ultrasonography is effective for imaging superficial organs, such as the scrotum. Using a highfrequency transducer, ultrasonography can identify the location and characteristics of scrotal lesions with high accuracy. The primary role of ultrasound (US) in the evaluation of a scrotal mass is to determine if it is intratesticular or extratesticular. Additional clinical information and other imaging options may be needed to diagnose benign tumors and pseudo-tumors. MRI is an effective problem-solving tool in cases with nondiagnostic US findings. CT is helpful for staging testicular cancer and localizing undescended testis. This review covers the imaging features of testicular and extratesticular tumors.

음낭 종양은 고환, 부고환, 정삭, 고환막 등에서 발생하며 악성 가능성을 평가하는데 가장 중요한 요소는 병변의 위치이다. 추가적인 영상 소견과 임상 정보를 종합하여 효과적으로 진단할 수 있다. 초음파검사는 표재성 기관인 음낭을 관찰하기 용이하며, 우수한 영상 품질을 바탕으로 병변의 유무뿐만 아니라 위치와 성상까지 확인 가능하다. 초음파검사로 감별이 어려울 경우에는 자기공명영상을 이용하여 지방, 출혈, 섬유화, 조영증강 등 추가적인 종양의 특징을 확인하는 것이 진단에 도움이 된다. 전산화단층촬영은 고환암의 병기결정이나 복강 내 미하강고환의 위치를 탐색하는데 유용하다. 본 종설에서는 고환 내외에서 발생하는 음낭 종양의 영상 소견을 살펴보고자 한다.
