To describe a case of cystic dysplasia of the testis (CDT), an uncommon cause of scrotal swelling in the pediatric patient. Clinical, radiographic, and pathologic findings are discussed and the 10 previously reported cases are reviewed.
A 4-year-old boy presented with asymptomatic scrotal swelling and was found to have a palpable mass in the upper pole of the right testicle with evidence of partial transillumination. A scrotal ultrasound revealed testicular enlargement with multiple cystic changes suggesting teratoma and operative exploration was recommended.
Intraoperative findings included a multicystic mass in the right testicle with minimal normal testicular parenchyma. Subsequent inguinal orchiectomy was performed and pathologic examination revealed a benign, multilobulated configuration of cysts in the region of the rete testis with atrophy of the surrounding testicle. These findings were similar to those found in previously reported cases of CDT. Ipsilateral renal agenesis, a commonly associated anomaly, was also discovered in our patient.
CDT is a rare cause of the pediatric scrotal mass that requires a high index of suspicion for diagnosis based on well-described clinical and sonographic findings. When feasible, a testicular-sparing approach should be considered and all patients should undergo evaluation for associated urologic anomalies.
描述一例睾丸囊性发育异常（CDT）病例，这是小儿阴囊肿胀的一种罕见病因。讨论其临床、影像学及病理表现，并回顾此前报道的10例病例。
一名4岁男孩因无症状阴囊肿胀就诊，检查发现右侧睾丸上极可触及肿块，有部分透光迹象。阴囊超声显示睾丸增大，有多个囊性改变，提示畸胎瘤，建议手术探查。
术中发现右侧睾丸有一个多囊性肿块，正常睾丸实质极少。随后进行了腹股沟睾丸切除术，病理检查显示睾丸网区域有良性、多叶状囊肿结构，周围睾丸萎缩。这些发现与此前报道的CDT病例相似。我们的患者还发现了同侧肾缺如，这是一种常见的相关异常。
CDT是小儿阴囊肿块的罕见病因，基于明确描述的临床和超声表现，诊断时需要高度怀疑。可行时，应考虑保留睾丸的方法，所有患者均应接受相关泌尿系统异常的评估。
