Urachal Remnant Diseases: Spectrum of CT and US Findings

Computed tomography (CT) and ultrasonography (US) are ideally suited for demonstrating urachal remnant diseases. A patent urachus is demonstrated at longitudinal US and occasionally at CT as a tubular connection between the anterosuperior aspect of the bladder and the umbilicus. An umbilical-urachal sinus manifests at US as a thickened tubular. The urachus (plural: or urachuses or urachi 6,7) is the fibrous vestigial remnant of the embryonic allantois.. The lumen of the urachus usually obliterates following birth and becomes known as the median umbilical ligament which is in turn covered by a midline linear fibrous fold of parietal peritoneum (the median umbilical fold) 3.This fold extends from the apex of the bladder to the umbilicus Urachal remnants are present in almost 100% of infants at birth and regress due to fibrosis with age, eventually becoming the median umbilical ligament. Two-thirds of adolescents and one-third of 35-year-old adults show remnant urachal tissue, but it is seen in only 3% of the general population at autopsy (13-16) Urachal remnant radiology discussion including radiology cases. Etiology: urachus is canal connecting bladder of fetus with allantois which is a structure that contributes to formation of umbilical cord, lumen of urachus normally obliterated during embryonic development, transforming urachus into solid cord / functionless remnant — Patent urachus - bladder communicates with umbilicu

The urachus is the remnant of the cloaca and allantois, and attaches the umbilicus to the bladder dome. Urachal anomalies are symptomatically identified during childhood. It rarely occurs in adults, making diagnosis difficult. We present and discuss the case of an infected patent urachus in a 30-year-old male Urachal remnant can be seen incidentally in up to 32% of adult bladder autopsies or cystectomies. Image C. Image D. In <20 years old are mostly lined by urothelial cells (95%), and with higher proportion of columnar cells with or without Goblet cells (30%) in older adults Urachal carcinoma tends to present with a much larger extravesical component than primary bladder cancer arising from the mucosa of the bladder apex. Differentiating urachal carcinoma from other urachal disease such as infected urachal remnants and benign urachal tumours can be problematic Urachal remnants may be found in midline or posterior bladder wall Remnants seen at autopsy in 50% of fetuses, 33% of adults Remnants are associated with urachal cysts, sinus, fistula, diverticulum, infections, adenocarcinoma of bladder; also urothelial carcinoma, villous adenoma, squamous cell carcinom Urachal adenocarcinoma can be difficult to distinguish radiologically from an infected urachal cyst, as both may appear as mixed cystic/solid masses in the pathway of the urachal remnant. Urachal cysts are generally asymptomatic congenital anomalies of the urachus, but they can become infected or give rise to malignancy and lead to their detection

In a minority of cases, urachal tract remnants undergo malignant transformation to urachal cancer, a very rare cancer that represents 0.5% of bladder malignancies; of these, 85-90% is adenocarcinomas [1]. Urachal adenocarcinomas have a 2:1 male predominance, and patients typically present in midlife [1] Imaging for a suspected urachal abnormality typically occurs during the newborn period. Ultrasound is the initial study for urachal anomalies . Ideally, imaging should be performed when the bladder is full to better show the close relationship between the dome of the bladder, umbilicus, and urachal remnant

While umbilical-urachal sinus appears as focal dilatation at the umbilical end of the urachal remnant, the vesico-urachal diverticulum presents as a focal outpouching of the urinary bladder at anterosuperior aspect. Urachal cysts are identified as midline fluid-filled sacs most frequently located near the dome of the urinary bladder Patients with urachal remnants may present with urinary infection, periumbilical fluid discharge, or a palpable lower abdominal mass.

Urachal carcinoma is a rare and aggressive form of bladder cancer involving the urachus, a fibrous remnant of the allantois that extends from the bladder to the umbilicus. We report this case of a 49-year-old women with primary urachal adenocarcinoma treated with partial cystectomy who relapsed 5 years after surgery with lung metastases We undertook this study to evaluate the frequency of visualization and the sonographic appearances of urachal remnants (URs) in asymptomatic children. Methods One hundred eighty‐two children without any urachus‐related symptoms underwent sonography of the prevesical region and urinary bladder with high‐frequency transducers This entails excision of the bladder dome and the urachal remnant along with its peritoneal, fascial, and umbilical segments. 2, 6, 8, 15, 16 It is unclear whether lymphadenectomy, radiation, or chemotherapy are of any benefit to patients with urachal carcinioma. 2, 15 The urachal sinus is a vestigial remnant that ensues in the aftermath of incomplete obliteration of the embryonic urachus. Urachal sinuses often remain asymptomatic, being discovered incidentally in instances where they are complicated with a superimposed infection or abscess. Due to their rare occurrence in adults, urachal sinuses are rarely included in the list of differential diagnosis. Yu JS et al: Urachal remnant diseases: spectrum of CT and US findings.

As such, this is the first case to describe calcification within a urachal remnant so close to its insertion into the urinary bladder that it mimics a bladder calculus on axial imaging. The urachus is a vestigial remnant of the allantois (derivative of yolk sac) and the cloaca (precursor of the foetal bladder) anomalies. In a minority of cases, urachal tract remnants undergo malignant transformation to urachal cancer, a very rare cancer that represents 0.5% of bladder malignancies; of these, 85-90% is adenocarcinomas [1]. Urachal adenocarcinomas have a 2:1 male predominance, and patients typically present in midlife [1] Radiology: 1-Plain Film: Rarely, urachal cyst will calcify; Urachal diverticula may have calcified stones or tumoral calcifications; 2-SINOGRAM: Fistulogram will outline the inferior extent of a urachal sinus from the umbilicus; Will demonstrate a patent urachus 3-CYSTOGRAM The remnant with tumor extended into the upper half (5) or lower half (3) of muscularis propria (MP) and if misinterpreted as MP invasion, 5 of 8 bladder tumors will be overstaged.

Urachal cancer is a form of cancer that arises in a structure called the urachus. The urachus is a canal that exists when the fetus is developing before birth. This canal runs from the bladder of the fetus to the belly button (umbilicus). It drains the urinary bladder of the fetus di erentiate between infected urachal remnants and urachal carcinomas. Cysts with mural nodularity and calci cation in contrast-enhanced computed tomography (CECT), as well as hematuria and the absence of ndings of infection in the perilesional so tissues, are usually signs of malignancy [ ].

Developed by CHOC physicians, in partnership with community physicians, these guidelines provide you with useful information in working up your patients, and contribute to making the appointment itself most meaningful by having the right clinical information available We report our experience with the laparoscopic excision of urachal remnants as a less morbid, minimally invasive surgical alternative. Materials and Methods: Between October 1993 and December 1999, 4 patients with a mean age of 43.3 years who had a symptomatic urachal cyst underwent laparoscopic radical excision of the urachal remnant Four types can be found: patent urachus, urachal sinus, urachal diverticulum and urachal cyst. The urachal cyst occurs when the urachus encompasses a cyst-like structure that is closed to the umbilicus and the bladder lumen. The urachus becomes a cystic structure since its epithelium is still intact, active and accumulating fluid, like the one.

The basic investigation tool for diagnosing a case of a urachal remnant is ultrasonography. The traditional approach for treatment of urachal anomalies is open excision. However, the trend has started to shift toward a laparoscopic approach, which has a promising future for dealing with urachal anomalies Urachal cyst symptomatology is solely exhibited upon complications, commonly infection. In such a case, antibiotic treatment and total surgical excision of the urachal remnants are mandatory, for fear of malignant development on urachal grounds [9] [12]. This is traditionally done with open surgery, which, however does increase morbidity, as. Abdominal Imaging offers a highly illustrated, case-based preparation for board review to help residents and recertifying radiologists succeed on exams, demonstrate a clinical understanding of gastrointestinal and genitourinary imaging, and improve imaging accuracy and interpretation. Cases include both common and difficult-to-diagnose. The urachus is an embryologic remnant which degenerates after the birth. Defective obliteration of the urachus leads to urachal abnormalities. An infected urachal cyst is one of the urachal abnormalities and this pathology is rare in adult women
