Intrathoracic renal ectopia as a result of a congenital diaphragmatic hernia (CDH) is a rare congenital anomaly. We present a case in which the prenatal diagnosis of an ectopic intrathoracic kidney was made on routine anatomical survey at 28 weeks' gestation. Color doppler sonography imaging revealed the renal artery coursing into the infant's thorax and was consistent with CDH, but fetal MRI suggested an intact diaphragm. However, neonatal evaluation confirmed the diagnosis of intrathoracic kidney with posterior CDH, which was repaired without complication. In contrast to diaphragmatic hernia with liver or bowel herniation, infants with intrathoracic ectopic kidneys generally do well.
先天性膈疝（CDH）导致的胸腔内肾异位是一种罕见的先天性异常。我们报告一例在妊娠28周进行常规解剖检查时产前诊断为胸腔内异位肾的病例。彩色多普勒超声成像显示肾动脉进入婴儿胸腔，与CDH相符，但胎儿MRI提示膈肌完整。然而，新生儿评估证实为胸腔内肾合并后位CDH，手术修复无并发症。与伴有肝脏或肠疝的膈疝不同，胸腔内异位肾的婴儿通常情况良好。
