To demonstrate the visualization of penile abnormalities on fetal magnetic resonance imaging (MRI).
This retrospective study included five fetuses (25+0 to 31+6 gestational weeks) with penile abnormalities, positively depicted on fetal MRI, using prenatal ultrasonography (US) as a standard of reference. On MRI, the penis, as well as the scrotum and testicles, were evaluated. All fetal organs were reviewed to define penile abnormalities as isolated or in association with other anomalies. Furthermore, US and MRI findings were compared.
Posterior hypospadias were demonstrated in all five fetuses, and abnormal testicular descent in two. Associated anomalies were present in all five fetuses on MRI, including abdominal/urogenital pathologies in four; brain pathologies in three; and craniofacial, cardiac, musculoskeletal, pathologies each in one fetus, and intrauterine growth retardation in one fetus. Compared to US, additional MRI findings were shown in four of five fetuses.
Our MRI results demonstrate the visualization of fetal penile abnormalities and associated pathologies, which may provide information for perinatal management. MRI may show additional findings compared to prenatal US in certain cases.
展示胎儿磁共振成像（MRI）上阴茎异常的可视化。
本回顾性研究纳入了 5 例（25+0 至 31+6 孕周）阴茎异常胎儿，产前超声（US）作为参考标准，对其 MRI 上的阳性表现进行评估。MRI 评估阴茎、阴囊和睾丸。所有胎儿器官均进行了检查，以确定阴茎异常是孤立性的还是与其他异常相关。此外，比较了 US 和 MRI 的发现。
5 例胎儿均表现为后尿道下裂，2 例睾丸下降异常。5 例胎儿在 MRI 上均存在合并畸形，包括 4 例腹部/泌尿生殖系统病变、3 例脑病变、1 例颅面、心脏、肌肉骨骼病变，宫内生长受限 1 例。与 US 相比，4 例胎儿的 MRI 还显示了其他发现。
我们的 MRI 结果显示了胎儿阴茎异常和相关病变的可视化，这可能为围产期管理提供信息。在某些情况下，与产前 US 相比，MRI 可能会显示出更多的发现。
