Neonatal orchitis is an extremely rare disease, usually related to a congenital genitourinary anomaly. We present a 36 weeks' gestation infant who presented at 3 days old with a firm and enlarged right testicle. Testicular US revealed a heterogeneous right testicle with numerous cystic spaces as well as decreased testicular blood flow. The clinical concerns included testicular tumor and cystic dysplasia of the testis because of concurrent renal dysplasia. The scrotal/testicular area was without tenderness or overlying erythema. Radical inguinal orchiectomy revealed diffuse gram-negative orchitis.This case represents an atypical presentation of orchitis. This entity should be added to the differential diagnoses of testicular mass in the neonate even in the absence of physical findings suggestive of infection.
新生儿睾丸炎极为罕见，通常与先天性泌尿生殖系统异常有关。我们报告了一例 36 周妊娠的婴儿，他在 3 天大时出现右侧睾丸坚硬且肿大。睾丸超声显示右侧睾丸不均匀，有许多囊性空间，睾丸血流减少。临床关注点包括睾丸肿瘤和睾丸囊性发育不良，因为同时存在肾发育不良。阴囊/睾丸区域无触痛或红斑。根治性腹股沟睾丸切除术显示弥漫性革兰氏阴性睾丸炎。本例代表睾丸炎的非典型表现。即使没有提示感染的体格检查发现，这种疾病也应纳入新生儿睾丸肿块的鉴别诊断中。
