背景/目的：泄殖腔畸形是罕见的异常，发生于女性，其尿道、阴道和直肠有一个会阴口。泄殖腔畸形的产前超声检查（US）有时会显示腹水、阴道积水和肾积水。我们在此描述了与胎便性腹膜炎相关的泄殖腔畸形的特征性产前超声和磁共振成像 (MRI) 结果。方法：回顾了 1988 年至 2004 年在我院治疗的 11 例泄殖腔畸形新生儿的产前和产后记录。所有胎儿均由经验丰富的产科医生进行了产前超声检查，此外，1 名患者还进行了胎儿 MRI。 结果：产前超声和/或 MRI 结果显示，11 例泄殖腔畸形患者中，5 例出现胎儿腹水、多囊性盆腔肿块、羊水过少和双侧肾积水。 5例产后检查均伴有阴道积水、子宫积水、双侧肾积水；此外，这5例中的4例在剖腹探查时也出现胎便性腹膜炎。结论：产前超声和MRI检查结果显示胎儿腹水、多囊性盆腔包块、双侧肾积水和羊水过少，高度提示与胎粪性腹膜炎相关的泄殖腔畸形。 (C) 2007 Elsevier Inc. 保留所有权利。
Background/Purpose: Cloacal malformations are rare anomalies, occurring in females, and in which they demonstrate a single perineal orifice for urethra, vagina, and rectum. Prenatal ultrasonograms (US) of cloacal malformations sometimes show ascites, hydrocolpos, and hydronephrosis. We herein describe the characteristic prenatal US and magnetic resonance imaging (MRI) findings of the cloacal malformations associated with meconium peritonitis.Methods: The pre- and postnatal records of 11 newborn patients with cloacal malformations, treated in our hospital from 1988 to 2004, were reviewed. All fetuses underwent prenatal US by experienced obstetricians, whereas in addition, fetal MRI was performed in 1 patient.Results: The prenatal US and/or MRI findings showed fetal ascites, a multicystic pelvic mass, oligohydramnios, and bilateral hydronephrosis in 5 of 11 patients with cloacal malformations. In these 5 cases, postnatal examinations showed associated hydrocolpos, hydrometrocolpos, and bilateral hydronephrosis; furthermore, 4 of these 5 cases also showed meconium peritonitis at laparotomy.Conclusions: The prenatal US and MRI findings, showing fetal ascites, multicystic pelvic mass, bilateral hydronephrosis, and oligohydraminios are highly suggestive of the cloacal malformations associated with meconium peritonitis.
