“…Differential diagnosis with omphalocele [12] or bladder exstrophy [13] is frequently difficult or even impossible, even though its management and prognosis are markedly different [14] . Both omphalocele and urachus cyst can present as a cystic mass arising from the ventral wall of the fetus with the umbilical cord inserting into the ventral mass.…”

Patent urachus cyst is a rare umbilical anomaly, which is poorly detected prenatally and frequently confounded with pseudo bladder exstrophy or omphalocele. A 27-year-old woman was referred to our prenatal diagnosis centre at 18 weeks of gestation after diagnosis of a megabladder and 2 umbilical cord cysts. Subsequent 2D, 3D and 4D ultrasound examinations and fetal magnetic resonance imaging (MRI) revealed a typical umbilical cyst and an extra-abdominal cyst, communicating with the vertex of the fetal bladder through a small channel that increased in size when the fetus voided urine. Termination of pregnancy occured at 31 weeks because of associated cerebral septal agenesis, and autopsy confirmed the prenatal diagnosis of urachus cyst. Few cases of urachus cyst diagnosed prenatally are reported in literature, but none were associated with other extra-abdominal disorders and none used 3D, 4D and fetal MRI. Our case illustrated the efficiency in prenatal diagnosis of 3D and 4D ultrasound examinations. This could help pediatrician surgeons to explain to a couple about neonatal surgical repair and plastic reconstruction in the prenatal period.

“…Today, the antenatal diagnosis of bladder exstrophy remains complex and misleading and is furthermore rarely reported in the literature [12]. The persistent absence of visualization of the bladder is one of the key ultrasound signs for the diagnosis of bladder exstrophy, but it is present in only 71% of cases and, moreover, the bladder can be falsely visualized [4].…”

Objective: To demonstrate the feasibility of measuring the fetal pubic diastasis (PD) distance on antenatal ultrasound in normal fetuses and to compare it to fetuses with bladder exstrophy. Methods: Firstly, a prospective multicentric study was conducted to determine the feasibility of the PD ultrasound measurement during the second half of pregnancy. Secondly, data from a single center were used to develop a nomogram for PD values in normal fetuses. Thirdly, retrospective PD measurements were collected from fetuses with bladder exstrophy, diagnosed in seven French Multidisciplinary Centers for Prenatal Diagnosis (MCPDs). Results: Operators from several MCPDs examined 868 fetuses and found that overall PD ultrasound measurement was feasible in 71% of cases and that the ossification of pubic points increased to be always visible from 27 weeks of gestation onward. Performed in a single center by a referring operator on 1,539 fetuses, the feasibility reached 94.74%. Both set of measurements were concordant (mean PD distance value of 5.42 ± 1.8 mm). Interestingly, all 23 fetuses with bladder exstrophy showed a significantly larger PD distance (mean 15.74 ± 3.9 mm). Conclusion: PD measurement in the fetus is feasible and reliable in the second half of gestation and can be used to support the antenatal diagnosis of bladder exstrophy with PD values exceeding 10 mm.

“…L'examen 2D doit permettre de rechercher des signes échographiques souvent associés [1,7,9] : une insertion basse du cordon ombilicale qui est inconstante ; une masse solide à la partie inférieure de la paroi abdominale correspondant à la plaque vésicale plus ou moins bourgeonnante, avec ou sans repli(s) ( Les extrophies vésicales sont souvent isolées, mais l'échographiste doit rechercher également les anomalies pouvant être associées aux coelosomies inférieures et entrant alors dans une association syndromique : l'omphalocèle, la fistule rectovésicale, l'agénésie du côlon terminal, l'imperforation anale, la malformation des organes génitaux externes ou encore une malformation des membres inférieurs [2]. D'autres anomalies sont également plus fréquentes et sont donc à rechercher : anomalies cardiovasculaires, rénales, squelettiques et du système nerveux central [2].…”
