“…[ 13 ] CM is commonly found in female newborns. [ 2 , 3 , 5 , 6 , 11 , 13 , 14 , 17 ] As far as we know, only 2 male neonates have been reported in the literature. [ 4 , 8 ] Depending on the different stages of development stop, it will lead to various spectrum malformations, ranging from urogenital sinus to cloacal dysgenesis.…”

“…This may be because the genital tract and urinary tract are interconnected due to the developmental malformation, ultimately resulting in communication signals. [ 14 ] In this study, we can clearly observe the positional relationship among intestine, vagina, and bladder with the aid of MRI. Therefore, MRI is beneficial to evaluating pelvic anatomy, rectal contents, and abnormalities when the prenatal US cannot make a definitive diagnosis.…”

Rationale: Cloacal malformation (CM) is a serious type of anorectal and urogenital tract malformation. However, prenatal ultrasound (US) detection of CM is challenging. In this paper, we reported a rare case of CM prenatally diagnosed by US and magnetic resonance imaging (MRI), as well as reviewed the prenatal US and MRI characteristics of CM in the literature. Patient concerns: A 30-year-old pregnant woman complained of cystic mass in the fetal abdomen detected by prenatal US. Diagnosis: Fetus CM. Interventions: The fetus was diagnosed as fetal CM by US and MRI, then the pregnant woman received a drug-induced labor treatment. After the neonate was delivered, the measurement was performed on the weight, length, head circumference, abdomen circumference, and bilateral thigh circumference. Outcomes: A female dead neonate was delivered from the vagina of the gravida, showing congenital anus absence. Prenatal ultrasound demonstrated right kidney duplication, hydronephrosis, and right ureteral dilatation. Meanwhile, prenatal MRI showed a cystic cavity, double collecting systems of right kidney, right ureteral dilatation, and right rectum dilatation. In addition, general parameters are as follows: weight: 2280 g; length: 39 cm; head circumference: 26.3 cm; abdomen circumference: 31 cm; right thigh circumference: 17 cm, and left thigh circumference: 18 cm. Lessons: US combined with MRI can not only provide reliable evidence for fetal CM in the third trimester but also offer crucial information to the pregnant women to establish clinic treatment programs as early as possible.

“…Next to ruling out associated anomalies or absence of the rectum, estimating of the length of the common channel may be helpful for the pediatric surgeon in parental counseling, given it affects urinary prognosis . The use of fetal MRI in simple conditions, such as isolated hypospadias is questionable, since it does not impact management nor counseling …”

The use of fetal MRI for renal and urogenital tract anomalies

et al. 2019

Fetal anomalies are detected in approximately 2% of all fetuses and, among these, genitourinary tract abnormalities account for 30% to 50% of all structural anomalies present at birth. Although ultrasound remains the first line diagnostic modality, fetal MRI provides important additional structural and functional information, especially with the development of faster sequences and the use of functional sequences. The added value of MRI-based imaging is three-fold: (a) improvement of diagnostic accuracy by adequate morphological examination, (b) detection of additional anomalies, and (c) in addition, MRI has the potential to provide information regarding renal function. In this review, we describe the role of fetal MRI in the anatomical evaluation of renal and urogenital tract anomalies, and we also touch upon the contribution of functional MRI to the diagnostic workup of these conditions.

“…Although rare, pelvic cystic masses can lead to a suspicion of an obstructive urogenital malformation . These malformations include obstructive uropathy, obstructive genital anomaly, combined obstructive urogenital anomaly, or cloacal anomalies . These anomalies represent a range of different pathologies, each carrying very different prognosis.…”

“…Ultrasound (US) examination has proven insufficient to distinguish isolated hydrocolpos from cloacal dysgenesis, as these malformations display similar prenatal patterns . Recent literature has emphasized the potential role of fetal magnetic resonance imaging (MRI) in urogenital malformations . Indeed, it is highly important to identify cloacal malformations, as they carry a much poorer prognosis.…”
