A 10-month-old infant was referred for disappearance of the left testis, which had been confirmed as present on antenatal ultrasound at 38 weeks of gestation, as well as at the newborn physical exam and the 4 month exam. The right testis was enlarged, whereas the left testis was palpated as a nubbin. The right testis measured on ultrasound was 1.6 × 0.8 × 1.0 cm; the testicular volume was 0.67 cm(3). The left nubbin was hyperechoic, and accurate measurement of testicular components was difficult. At the age of 1 year 8 months, with the diagnosis of left vanishing testis, inguinal exploration was undertaken to rule out intra-abdominal cryptorchidism. A fibrous nodule that connected to the spermatic vessels and the vas deferens was resected. Histopathology indicated a testicular remnant containing seminiferous tubules, hemosiderin deposits, calcification and marked fibrosis of the stroma, suggesting hemorrhagic infarction in utero.
一名10个月大的婴儿因左侧睾丸消失前来就诊，该睾丸在妊娠38周时的产前超声检查、新生儿体格检查以及4个月检查时均被确认为存在。右侧睾丸增大，而左侧睾丸触诊为一小结节。超声测量右侧睾丸大小为1.6×0.8×1.0厘米；睾丸体积为0.67立方厘米。左侧小结节回声增强，难以准确测量睾丸各部分。在1岁8个月时，诊断为左侧睾丸消失，进行腹股沟探查以排除腹腔内隐睾。切除了一个与精索血管和输精管相连的纤维性结节。组织病理学显示睾丸残余物含有生精小管、含铁血黄素沉积、钙化以及间质明显纤维化，提示宫内出血性梗死。
