Review
The incidence of congenital urachal, bladder, and cloacal anomalies is low. Urachal remnants are the result of failure or delay in obliteration of the allantois. Exstrophy of the bladder or cloaca can be diagnosed on prenatal ultrasonography and represent a deviation from the normal embryologic sequence. Persistent cloaca is an anomaly occurring in girls, in which a common cavity exists into which the intestinal, urinary, and reproductive tracts all open. It is also often diagnosed on prenatal imaging.

A free-living, female Grevy's zebra (Equus grevyi) foal was found lethargic, lame, with swollen joints, pyrexia, and urine dripping from the umbilicus. It died 2 days later despite intensive care. Gross examination revealed patent urachus and suppurative arthritis. Swabs were taken from the joints, the patent urachus, and urine for bacteriology. The dominant isolate was Escherichia coli. The joint infection was probably secondary to septicemia, resulting from the patent urachus. To our knowledge, this is the first report of neonatal patent urachus in a wild equid.

Review
The space of Retzius is an important anatomic location for pathology. Pathology in the space of Retzius is more common than previously believed, especially as more cases are discovered with increased use of cross-sectional imaging. Knowledge of the anatomy of the Space of Retzius is crucial for identifying and distinguishing between benign and pathological findings. This paper uses several case examples to discuss benign etiologies, including normal tissue or a foreign body. The paper also demonstrates a case series with pathologic findings in the Space of Retzius under the broad categories of infection, neoplasm, hemorrhage, or urine extravasation. Understanding of the anatomy and these example cases can improve the diagnostic accuracy of radiologists.

The urachus is an embryonic remnant that connects the primitive bladder to the allantois. Multiple urachal anomalies have been described, including the urachal sinus, urachal cyst, patent urachus, and urachal diverticulum. We describe an unusual case in which a patient with urinary tract infection and dysuria was ultimately found to have urinary gallstones from a urachal connection with the gallbladder.

A long diffuse giant umbilical cord (GUC), caused by umbilical cord edema associated with a patent urachus, is an extremely rare anomaly. While patients with diffuse GUC appear to experience no significant complications and a good prognosis, little is known about their etiology and prenatal course. Here, we report the first case of prenatally diagnosed diffuse GUC resulted from patent urachus in a monochorionic diamniotic twin with selective intrauterine growth restriction. This case indicates that GUC is epigenetic and unrelated to multiple births.

Patent urachus results when there is a persistence of an allantois remnant which normally undergoes atresia during embryological development. It can lead to an abdominal wall defect similar in appearance on ultrasound to an omphalocele. A 34-year-old primigravida presented at 19 weeks' gestation for evaluation of a cystic mass arising at the umbilical cord insertion. The initial impression of the referring physician was an omphalocele. The mass arose from the abdominal wall and the umbilical cord inserted into the membranous covering of the mass, which appeared to be fluid-filled and separate from but contiguous with the urinary bladder. Serial sonography followed the progression of the abdominal wall mass. At term, the patient underwent primary Cesarean section with delivery of a 4494-g male infant. The infant underwent repair and closure of the patent urachus and plastic reconstruction of the abdominal wall. When the urachus remains patent, it can lead to a urinary fistula which mimics the ultrasound appearance of an omphalocele. However, patent urachus is associated with a much lower rate of abnormalities than omphalocele, yielding a better fetal prognosis.

Review
A case of persistent permeability of the medial umbilical fold identified by the ultrasound detection of an enlarged umbilical cord. The ultrasound characteristics of this cord are described. A review of the literature made it possible to survey the diagnostic conditions of this disorder and to envisage the mechanisms involved.
