| 目的 观察胎儿腹腔型隐睾畸胎瘤超声表现。方法 回顾性分析本中心1例腹腔型隐睾畸胎瘤新生儿、结合文献报道的8例,观察胎儿腹腔型隐睾畸胎瘤超声表现。结果 9胎腹腔型隐睾畸胎瘤均为男胎,产前超声显示包块最大径12~50 mm、平均(26.00±10.52)mm,均为腹腔内囊性(3胎,均无钙化)或囊实性回声(6胎均见钙化);4胎畸胎瘤源于左侧隐睾、5胎来自右侧隐睾,左侧者位于膀胱左侧、右侧者位于右髂窝/右肾前方。4胎接受阴囊扫查均仅见单侧睾丸回声,其中3胎诊断为隐睾畸胎瘤、1胎考虑腹膜后畸胎瘤可能;5胎未经扫查睾丸而误诊为肠系膜囊肿、腹膜后肿瘤或腹腔[LM]包块。9例产后超声均表现为囊实性回声,术后病理均提示成熟型畸胎瘤。胎儿腹腔型隐睾畸胎瘤内部回声在孕中期与晚期之间差异无统计学意义(P＞0.05)。结论 腹腔型隐睾畸胎瘤产前超声主要表现为腹腔内囊性或囊实性包块、其内可见钙化而无血流,且扫查阴囊时仅见单侧睾丸。 |

| Objective To observe the ultrasonic manifestations of fetal intra-abdominal testicular teratoma. Methods Prenatal ultrasonic manifestations of fetal intra-abdominal testicular teratoma were retrospectively analyzed based on 1 neonatus with intra-abdominal testicular teratoma in our center and 8 cases in literature. Results All 9 fetuses with intra-abdominal testicular teratoma were male ones. Prenatal ultrasound showed masses with the maximum diameter of 12 to 50 mm, with an average of (26.00±10.52) mm, which presented as cystic (3 fetuses, without inside calcification) or cystic-solid echoes in the abdomen (6 fetuses, with inside calcification). The tumor in 4 fetuses originated from the left cryptorchidism and located on the left side of bladder, while in 5 fetuses from the right cryptorchidism and located in the right iliac fossa or in front of the right kidney. Scrotal scanning was performed in 4 fetuses, during which only unilateral testicular echo was observed, and 3 were diagnosed as testicular teratoma and 1 was suspected of retroperitoneal teratoma. Five fetuses did not receive bilateral testicular scanning, which were misdiagnosed as mesenteric cysts, retroperitoneal tumors or abdominal masses. Postpartum ultrasound showed cystic-solid echoes in all 9 cases, which were all diagnosed as mature teratoma by postoperative pathology. No significant difference of internal echoes of intra-abdominal testicular teratoma was found between the second and third trimesters (P＞0.05). Conclusion Fetal intra-abdominal testicular teratoma presented as cystic or cystic-solid masses being able with internal calcification but without vascularity in the abdominal cavity in prenatal ultrasound, and only one side testis visualized during scrotal scanning. |
