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.

Hepatic ciliated foregut remnants or cysts are congenital abnormalities resulting from retention of embryonic ciliated foregut within the liver. These structures are rarely reported in the human medical literature and have not been reported in the veterinary literature previously, to our knowledge. We describe here a case of an 8-wk-old male French Bulldog with a congenital patent hepatic ciliated foregut remnant resulting in an umbilicobiliary sinus tract. The dog also had concurrent gallbladder agenesis. The patient had yellow fluid discharging from the umbilicus, mimicking a patent urachus. Surgical exploration, removal, and histology provided a conclusive diagnosis of a hepatic foregut remnant and therapeutic resolution of the clinical signs. The histologic appearance of a hepatic foregut remnant is classical, namely a duct composed of 4 layers: an inner ciliated epithelial lining, loose connective tissue, smooth muscle, and a fibrous capsule.

The urachus is an embryonic tube that connects the upper portion of the bladder to the umbilicus, and obliterates normally during embryonic development stages forming the median umbilical ligament. Incomplete obliteration of this tube results in many anomalies such as congenital patent urachus, umbilical urachal sinus, vesicourachal diverticulum and urachal cyst. We report in this case a 5-year-old female presented to the Emergency, complaining of generalized abdominal pain, fever, vomiting, and constipation with no umbilical discharge. The clinical presentation accompanied by radiology investigations suggested a case of acute abdomen. We performed an exploratory laparotomy and found a mass above the bladder connected to the umbilicus; we excised the mass and sent a specimen to pathology that confirmed Urachal cyst. Urachal cyst is usually asymptomatic unless it is complicated; depending on our case, we recommend surgical management by complete excision for complicated urachal cyst.

Urorectal septum malformation sequence is a sporadic malformation due to failure of septation of primitive cloaca with no anal opening. Umbilical cyst can be associated with chromosomal aneuploidy such as trisomy 18 or trisomy 13. We report on a fetus with complete urorectal septum malformation sequence with an umbilical cyst resulting from a patent urachus and with meconium as its content. This report adds to the variety of the causes of umbilical cyst and the spectrum of consequences of urorectal septal defect.

The urachus is a vestigial structure of the allantois and cloaca. It involutes as fetal development progresses to become a fibrous cord, which courses between the umbilicus and bladder dome within the retropubic space. Infection occasionally occurs in patients with congenital patent urachus. Here, we report a patient with infection of a previously closed urachal tract presenting as an abdominal mass. This has rarely been described in the literature. Current knowledge on imaging findings to the diagnosis is discussed.

The objective of this study is to define optimal diagnosis and treatment strategies for patients with urachal anomalies in the pediatric age group. The medical records of 21 children who had undergone surgery for urachal anomalies at Severance Hospital, Yonsei University College of Medicine from January 1990 to April 2005 were reviewed. The subjects included 14 males and 7 females (M:F 2:1). The four types of urachal anomalies confirmed were a urachal cyst in 10 patients (47.6%), a patent urachus in 6 (28.6%), a urachal sinus in 4 (19.0%) and a urachal diverticulum in 1 (4.8%) patient. The most common presenting complaint was umbilical discharge (n = 10, 40.0%), followed by abdominal mass (n = 9, 36.0%). Urachal anomalies were diagnosed by ultrasonography in 18 patients, and 7 of them were additionally examined by computed tomography. The remaining patients were diagnosed solely by surgical exploration. Excision was performed in all patients and was supplemented by partial cystectomy in three. Umbilical discharge was the most common clinical manifestation in our patients, suggesting that ultrasonography should be performed in patients with umbilical discharge to differentiate urachal anomalies. We found the most common anomaly to be the urachal cyst, and all patients were successfully treated by surgical excision.
