Abstract

Epidermoid cysts are benign simple epithelial tumors usually appearing as hypoechoic lesions with scattered echogenic reflectors on sonography. Herein, we present a 53-year-old man with an extratesticular epidermoid cyst in the right scrotum which shows confusing sonographic findings, normal-appearing echogenicity of the lesion and atrophied testis, which lead to a diagnostic dilemma. With a variety of sonographic presentations in extratesticular epidermoid cysts, magnetic resonance (MR) imaging could play a complementary role in difficult cases.

摘要

表皮样囊肿是良性的单纯上皮性肿瘤，通常在超声检查中表现为低回声病变，伴有散在的强回声反射。本文报道了 1 例 53 岁男性患者，右侧阴囊内存在附睾外表皮样囊肿，其超声表现较为混杂，病变呈正常回声且睾丸萎缩，这导致诊断较为困难。附睾外表皮样囊肿的超声表现多种多样，磁共振成像（MR）在疑难病例中可发挥补充作用。
