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 a tubular structure that is apparent on the third week and connects the ventral cloaca to the yolk sac, as a progression from the allantois. Following the normal regression procedure, the urachus remains as the median umbilical ligament. Urachal remnants are present in 1.03% of paediatric patients while in 92.5% of cases represent incidental findings. Urachal anomalies are classified in four types as patent urachus (50-52%), urachal sinus (15%), urachal cyst (30%) and urachal diverticulum (3-5%). Ultrasound scan is the most commonly performed diagnostic imaging study. In case of symptomatic urachal remnants, surgical excision is indicated. Asymptomatic urachal remnants that are diagnosed at the neonatal period or early infancy should be watched up to 6 months of age, as they are likely to resolve. In persistent or symptomatic urachal remnants there is a risk of inflammation or even malignancy development, therefore we believe that there is indication for preventive surgical excision that may be performed either open or laparoscopically or by robot-assisted laparoscopy.

In neonatal foals, umbilical remnants can be affected by infectious and non-infectious diseases. This study aimed to retrospectively evaluate historical, management and clinical factors that may be related to the occurrence of umbilical remnant diseases. Clinical reports of foals born or hospitalized within 24 h of life during the 2017-2021 foaling seasons were reviewed. Forty/183 foals (21.9 %) developed umbilical remnant diseases (URD group), while 143/183 foals (78.1 %) had normal umbilical remnants (NUR group). In the URD group, 24/40 (60 %) had a patent urachus, 16/40 (40 %) omphalo-arteritis, 4/40 (10 %) omphalo-phlebitis, 10/40 (25 %) urachitis, 9/40 (22.5 %) abscess, 3/40 (7.5 %) periumbilical hematoma and 12/40 (30 %) more than one condition. URD frequency was higher in foals hospitalized after birth than in those born at the hospital (17/46 vs 23/137; P = 0.0068), lower in those that had access to the paddock before three days of life (p = 0.0426) and higher in recumbent foals (P = 0.0001). URD occurred more frequently after dystocia (P = 0.0068), prolonged stage II parturition (19±20.51 min vs 13±6.41 in NUR group; P = 0.0279), traction at parturition (P = 0.0005), and in foals with lower APGAR scores (8±1.72 vs 9±0.86 in NUR; P = 0.0063). Sepsis (P = 0.0245), neonatal encephalopathy (P = 0.0014), meconium retention (P = 0.0241) and congenital flexural limb deformities (P = 0.0049) were the most common associated diseases. Umbilical cord (UC) coiling, abnormal UC rupture, umbilical hemorrhage and increased umbilical stump volume occurred more frequently in URD than in NUR group (P = 0.0329, P = 0.0191, P = 0.0007 and P < 0.00001, respectively). Recognition of the identified predisposing historical, management and clinical factors should prompt careful umbilical remnant monitoring in neonatal foals.

Congenital urethral atresia is generally considered to be incompatible with life unless there is either a patent urachus or vesicoamniotic shunt. Here we present the case of a male neonate with anhydramnios detected at 28weeks gestation due to urethral atresia, who was born without evidence of either a patent urachus or vesicoamniotic shunt, who has survived and is not requiring respiratory support at age 5months. While this is a thought-provoking clinical case, it also highlights the importance of early and effective parental engagement in cases of complex congenital anomalies of the urinary tract.

This is a case report about a patient presenting with a urachal mass mimicking a urachus adenocarcinoma. Cystoscopy showed a vesicourachal patent diverticulum. Histological findings after the removal of the umbilicus, urachus, urachal tumor, as well as a bladder cuff, consisted of a nonspecific polymorphous suppurative inflammatory infiltrate. Urachal adenocarcinoma is an aggressive tumor with poor prognosis if not treated while it is still localized. Surgical excision is the only recommended treatment that offers the best chances of survival. As no preoperative procedure has been proven accurate enough to rule out the diagnosis of adenocarcinoma, surgery appears to be inevitable.

Rare developmental anomalies known as urachal remnants are brought on by flaws in the foetal developmental process. However, depending on the location and degree of incomplete obliteration, the urachus can undergo a variety of urachal anomalies. An umbilical fistulogram and a voiding cystourethrogram both supported the existence of the adult urachal cyst in this case. To treat the sepsis, we provided the patient with antibiotics first, then a surgical procedure. The entire vesico-umbilical tract with the urachal cyst was removed using the open approach. The excised specimen's histology revealed a foreign body giant cell reaction without any indication of malignancy. The presentation and diagnosis of vesico-umbilical urinary fistula (VUUF) in adults can occasionally be difficult. They happen very rarely. So we began putting forward this case for the same reason.

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.

BACKGROUND
Abnormalities of the urachus include the patent urachus, cysts, sinus, and fistula. Each of these entities represents a failure of complete obliteration of the urachus. Contrary to other urachus anomalies, urachal cysts are usually small and silent unless they are infected. The diagnosis is often made during childhood. A benign noninfected urachal cyst discovered in adulthood is a rare condition.
CASE PRESENTATION
Herein we report two cases of benign noninfected urachal cysts in adults. The first case is a 26-year-old Tunisian white man who presented with complaints of clear fluid draining from the base of the umbilicus evolving for a week, with no other associated symptoms. The other case was 27-year-old Tunisian white woman who was referred to the surgery department with a history of intermittent draining of clear fluid from the umbilicus. The two cases had laparoscopic resection of urachus cysts.
DISCUSSION
Laparoscopy represents a good alternative for the management of persistent or infected urachus, especially when this is suspected, despite a lack of radiological evidence. Laparoscopy in the management of urachal cysts is safe, effective, and offers good cosmesis, with all the advantages of a minimally invasive approach.
CONCLUSION
Managing persistent and symptomatic urachal anomalies requires a wide surgical excision. Such intervention is recommended to prevent symptom recurrence and complications, most notably malignant degeneration. A laparoscopic approach offers excellent outcomes, and is recommended to treat these abnormalities.

Review
One of the typical complaints in the pediatric population is umbilical discharge. Among the congenital causes, remnants of omphalomesenteric duct or patent urachus are often detected. On a few occasions, multiple types of ectopic tissue are present. We describe histopathologic findings of two cases reported recently at our center as pediatric umbilical lesions with associated ectopic tissue. Histopathology of the excised mass confirmed the patent omphalomesenteric duct with ectopic gastric, duodenal, and colonic mucosa and pancreatic tissue in two patients with the clinical presentation of umbilical discharge. There were no associated congenital anomalies in these patients. The presence of multiple ectopic gastrointestinal mucosa and pancreas in the umbilical mass is unusual. Herein, we report these cases because of its rarity, multiple ectopic tissues, and reviewing the literature of the reported cases of multiple ectopic tissues.
