Contribution of Three-Dimensional Ultrasonography in Depicting Perineal Features in Cloacal Malformation

Abstract

Cloacal anomaly is a rare malformation with an incidence of 1 in 50,000 births. The definitive prenatal diagnosis of cloacal dysgenesis sequence is difficult. The use of three-dimensional (3-D) ultrasonography helps to describe the perineum and change diagnosis. In our case report, a large median genital structure was visualized, which was initially considered a penis-like structure, but the 3-D technique showed an enlarged bud. The urethral meatus was at the tip of this smooth structure. The lack of anal structure was clearly demonstrated.

Visualization of the Anal Dimple by Fetal MRI: Is It Feasible?

“…Recently, there has been an effort to use prenatal assessment of the AD as an indicator of presence or absence of underlying ARM. Most studies have sought to assess the AD by prenatal US [12][13][14][15], with few utilizing fetal MRI. To the best of our knowledge, this is the first study to assess the feasibility of fetal MRI in detecting the AD and compare it to US.…”

Male cloaca malformation: rare variant of anorectal malformation

“…With recent advances in antenatal diagnosis like 3D ultrasonography and fetal MRI, more and more cases of cloaca are likely to be picked up [13,14]. Whereas previously, it was thought that a cloacal anomaly refers to a female child; the word should be used with caution as more cases of a cloacal anomaly in males that may be associated with a higher mortality and associated anomalies are recognized.…”
