Teratoma of the intra-abdominal testis is a rare finding in infants. We describe the case of a full-term newborn treated for a calcified abdominal mass which was observed unexpectedly on prenatal sonography. An undescended right testis was also noted. During laparotomy, a twisted retroperitoneal tumor was found just above the right deep inguinal ring. Histological analysis revealed a mature teratoma of the intra-abdominal right testis. The tumor was removed and there was no recurrence at follow-up 1 year later. A teratoma should be considered in cases of fetal abdominal mass, especially when the testes cannot be detected in the scrotum by the 8th month. Prenatal sonographic diagnosis might be possible.
腹腔内睾丸畸胎瘤在婴儿中是一种罕见的发现。我们描述了一例足月新生儿的病例，该患儿因产前超声意外发现的钙化腹部肿块而接受治疗。还发现右侧睾丸未降。在剖腹手术中，在右侧腹股沟深环上方发现一个扭转的腹膜后肿瘤。组织学分析显示为腹腔内右侧睾丸成熟畸胎瘤。肿瘤被切除，1年后随访无复发。胎儿腹部肿块病例应考虑畸胎瘤，尤其是在第8个月时阴囊内无法检测到睾丸的情况下。产前超声诊断可能可行。
