Persistent cloaca represents the most complex deformity in female anorectal, vaginal, and urogenital malformations. Cloacal malformation is diagnosed in one of every 20,000 to 25,000 newborn girls, usually just after the baby is born. Colonic stenosis is very rare, with fewer than 15 cases reported in the literature. Five female infants with a persistent cloaca are presented with a review of previous case reports. With cloacal malformation, which is sometimes called persistent cloaca, the baby typically has just one opening on her perineum.

A PERSISTENT CLOACA is the conjunction of rectum, vagina, and urethra into a single common channel. Defining these differences is key to surgical planning and timely referral of selected cases to centers with the capabilities to manage the most challenging cases. A cloacal malformation is defined as an abnormal congenital confluence of the rectum, vagina, and urethra into a single common channel (see the image below). Antenatal ultrasound and fetal magnetic resonance imaging (MRI) can provide the important clues for prenatal diagnosis of cloacal malfor-mations [3]. persistent cloaca [1, 3, 4]. In this female fetus, the association of an anorectal malformation (high-type) and hydrometrocolpos with ascites and normal bladder with mild kidney pelvic dilation led to the prenatal diagnosis of a persistent cloaca. Citation: American Journal of Roentgenology. The defining anatomical feature of persistent cloacal anomalies (PC) is the confluence of the urethra, vagina, and rectum to form a common channel which opens via a single opening on the perineum at a site usually corresponding to the region of the external urethral meatus (Figure 1).

Liu and F. Tsai and Pei . The abnormality in the formation of the urorectal septum at five to eight weeks gestation causes the urethra, vagina, and rectum to merge into a single tube. Awareness of the usual prevalence, location, and sonographic appearance of cystic lesion can help suggest the most likely diagnosis. Fetal ascites can occur due to many heterogeneous disorders. J Pediatr Surg 54(10):2004-2011 The female psedohermaphrodites have typically female internal genitalia with female karyotype(46,XX) but the external genitalia are masculanized [2]. The length of the common canal was measured using MRI and fluoroscopy contrast study. A 29-year-old primigravida presented at 32 weeks of gestation with ultrasonographic evidence of fetal ascites, a cystic pelvic mass, hydronephrosis and oligohydramnios. The high incidence of associated anomalies (especially urologic and genital) is noted. A cloaca exists in all human embryos up to 4-6 weeks, at which time it becomes partitioned into the urogenital sinus and the rectum. The study was approved by the hospital internal review board. The persistent cloaca is one of the most complex and challenging developmental malformations. Pediatric Radiologist Dr. Christine Wallace and Dr. Jeremy T. Aidlen were part of a multispecialty team that helped to treat a young baby girl with a rare birth defect know as persistent cloaca. }, author={C. Chen and T. Chang and Chin-Yuan Hsu and Y.

This diagnosis has classic US and MRI findings and malformation. The diagnosis of CM is made when a female newborn has a single perineal orifice where the urethra, vagina and rectum converge to form a common channel, i.e. It is an embryonic structure (weeks 4-7) in which the distal ends of the gastrointestinal tract and urogenital system share a common channel. These three typically separate as a pregnancy proceeds, creating the anus, the vagina, and the urethra. AIM: To evaluate the role of MRI in preoperative assessments of patients with a persistent cloaca and compare magnetic resonance imaging (MRI) versus fluoroscopy contrast study in the accuracy of common canal measurement and classification prediction. It is associated with a wide spectrum of complex adolescence, and we have seen a significant proportion of them suffer from serious unpredicted abdominal prob- lems that require surgery.

Skondras KG, Moutsouris CC . Anatomically these anomalies are defined by the presence of a single perineal orifice. PURPOSE: The unique confluence of the urinary, genital and gastrointestinal tracts in girls with persistent cloaca potentially results in aberrant drainage of urine and meconium that may be characteristic, allowing a prenatal diagnosis to be made. It may be a part of a complex syndrome and can be more often associated with congenital malformations affecting the genitourinary tract system (33%) such as intersex, rectovaginal communication . Fifty female infants . Anatomically these anomalies are defined by the presence of a single perineal orifice. Persistent cloaca, cloacal malformation, or cloacal dysgen-esis sequence, is a rare congenital anomaly that typically affects females and has an incidence of 1:50,000.1 Persistent cloaca accounts for about 10% of all anorectal malformations in females.3 In birds and reptiles, persistent cloaca is normal. Persistent Cloaca • Persistent cloaca represents the most complex deformity in female anorectal, vaginal, and urogenital malformations. Overview: The colon is the least involved segment in intestinal atresias; colonic atresia constitutes between 1.8% and 15% of intestinal atresias, with an overall incidence of approximately 1 in 20,000 births. They are anorectal malformations that occur in females. The high incidence of associated anomalies (especially urologic and genital) is noted. Persistent cloaca (PC) is the most intricate anorectal malformation characterized by a convergence of the ure-thra, vagina, and rectum forming into a narrow common channel in the perineum [1,2]. Anorectal malformations comprise a wide spectrum of diseases, which can affect boys and girls, and involve the distal anus and rectum as well as the urinary and genital tracts. Lower urinary tract abnormalities were frequent (reflux . 37. This is an extremely rare abnormality, being seen in only 1 in 50,000 births.
