A rare case of infected urachal cyst leading to intestinal obstruction in a 3-month-old boy with febrile urinary tract infection: Case report.

RATIONALE: Urachal anomalies are rare and can present with various clinical manifestations. Urachal remnants, in particular, can be difficult to diagnose because of atypical symptoms at presentation. This study reports a case of intestinal obstruction in an infant secondary to an infected urachal cyst. PATIENTS CONCERNS: A 3-month-old boy with a known febrile urinary tract infection developed acute abdominal distension. DIAGNOSES: Abdominal ultrasound (US) and computed tomography (CT) revealed a nonspecific, ill-defined soft tissue density at the mid-abdomen, associated with intestinal obstruction. INTERVENTIONS: Emergency exploratory laparotomy was performed. The site of the obstruction was found to be at the mid-small bowel; the proximal small bowel was markedly distended, and the small bowel and sigmoid colon were adherent to urachal remnant. The urachal remnant was excised, and the peritoneal adhesions were lysed. OUTCOMES: The day after surgery, the patient was discharged without any complications. LESSONS: Intestinal obstruction is an exceedingly rare presentation of urachal remnants. This case highlights that urachal anomalies should be considered in the differential diagnosis in patients with intestinal obstruction and a concurrent febrile urinary tract infection.

Complicated urachal cyst in two pediatric patients: a case report.

BACKGROUND: A urachal cyst has a rare incidence that has been reported as 1/5,000 live birth. CASE PRESENTATION: We report two patients with a complicated urachal cyst, a 5-year-old female who presented to the emergency department with severe abdominal pain and a 3-year-old female presenting with abdominal pain and constipation. Upon laparoscopic exploration both patients had complicated urachal cysts which were adherent to the urinary bladder. CONCLUSION: Complicated urachal cysts can present with acute abdominal pain.

Prenatal Detection of Vesico-Allantoic Cyst: Ultrasound and Autopsy Findings.

Introduction: The vesico-allantoic cyst is a communication between the fetal bladder and the allantois through a patent urachus.Case Report: We describe a 17-week of gestational age (WGA) fetus with a 40 x 30 mm vesico-allantoic cyst. At 19 WGA, ultrasound (US) detected bilateral dilatation of renal pelvis (5-6 mm), hydroureters, and hypospadias. Amniotic fluid, umbilical cord flow, and fetal biometry were regular. Due to uncertain prognosis, the parents opted for legal termination of pregnancy. Autopsy confirmed the prenatal findings, also revealing intestinal malrotation and Meckel's diverticulum.Discussion/Conclusion: Probably an initial urinary tract obstruction occurred, not yet affecting the amniotic fluid volume, but evident as pyelectasis. This case highlights the possibility that genito-urinary and intestinal anomalies may be found in association with the vesico-allantoic cyst.

Dysuria, Rebound Tenderness, and a Palpable Mass-A Ticking Time Bomb.

A 37-year-old male presented to the emergency department with the complaint of periumbilical abdominal pain, radiating to just above pubic symphysis. The patient reported that the pain was worse with urination and associated with chills and nausea. This case reports discusses the Emergency Department (ED) course and subsequent treatment of a patient found to have an infected urachal cyst, a previously asymptomatic embryological anomaly in an otherwise healthy middle-aged adult male. This is a crucial diagnosis to make in order to avoid the potential for significant morbidity and/or mortality, given the unlikely symptomatic source.

[Urachal remnant and acute abdomen: when it's not what it seems].

Among the causes of acute surgical abdomen, infection of a urachal remnant may go unnoticed despite routine complementary studies. We present three cases in boys aged 11, 6, and 4 years who were brought to the emergency department for right iliac fossa pain, fever, and urinary symptoms. Examination and complementary tests results were compatible with acute complicated appendicitis and were sent to surgery. While in the operating room, appendicitis was excluded and inflammatory changes suggestive of infection of the urachal remnant were documented. Complications of urachal remnants should be considered in the differential diagnosis of acute surgical abdomen, since advanced infection of the urachus may be a cause of confusion. A more accurate presumptive diagnosis can change the therapeutic/surgical approach and follow-up.

Urachal Actinomycosis Presenting with Recurrent Urinary Tract Infections in a Middle-aged Woman: A Rare Case Report.

The urachal cyst, a remnant of allantois sac during embryogenesis, is a rare condition in adulthood. Urachus is an embryologic remnant degenerating after birth. Abberrant obliteration of the urachus causes urachal abnormalities. The urachal cysts are almost always symptomatic when infected. The symptoms include fever, abdominal pain, tenderness, lower abdominal mass, nausea, vomiting, and dysuria. Ultrasonography, computerised tomography, and magnetic resonance imaging techniques may be insufficient for diagnosis. In most cases, staphylococcus species are isolated from cultures of urachal cysts. Other microorganisms such as Escherichia coli, Enterococcus faecium, Klebsiella pneumonia, and rarely actinomyces may be isolated. Actinomyces, an anaerobic gram-positive filamentous bacterium, is a rare cause of granulomatous disease. In this case report, a 56-year woman with urachal cyst infection with actinomyces is discussed according to current knowledge. Key Words: Urachal cyst, Urachus, Chronic cystitis, Actinomyces.

Case of Infected Urachal Cyst in an Adult Presenting as an Incarcerated Umbilical Hernia.

The urachus is a remnant of the allantois. Failure to obliterate can result in one of four anomalies, urachal cyst being most common. Urachal cysts are relatively rare, especially in adults. This paper presents a patient with an umbilical hernia and a ruptured urachal cyst. A 39-year-old male presented with concern for umbilical hernia, but he also noted drainage. Computed tomography scan showed a urachal cyst and umbilical hernia. The urachal cyst was excised and umbilical hernia closed primarily. The incidence of an urachal cyst is unknown, but persists in roughly 2% of adults. Diagnosis is with ultrasound or CT scan. Management is excision due to risk of urachal carcinoma, which is present in over 50% of specimens. Review of literature did not reveal any other cases of a patient with both an urachal cyst and an umbilical hernia, thus making this case a unique presentation for this condition.

A rare case of eosinophilic cystitis involving the inside and outside of the urinary bladder associated with an infected urachal cyst.

BACKGROUND: Eosinophilic cystitis is a rare inflammatory disease of the bladder characterized by eosinophilic infiltration of the bladder wall. Most Eosinophilic cystitis cases present with mucosal lesions of the urinary bladder. We present a very rare case of large mass-forming eosinophilic cystitis, involving the inside and outside of the bladder associated with an infected urachal cyst. CASE PRESENTATION: A 59-year-old man presented with gross hematuria, fever, dysuria, and suprapubic pain. Computed tomography showed a heterogeneously enhancing mass that measured 7.6 cm × 4 cm located on the anterosuperior portion of the bladder with an internal fluid collection. Cystoscopy revealed a raspberry-like mass lesion on the bladder dome. Transurethral resection of the bladder was initially performed. The mass lesion protruding from inside the bladder was removed, and pus-like fluid was drained. The pathologic diagnosis was eosinophilic cystitis. Follow-up computed tomography showed a remnant mass outside the bladder and urachal cyst. To eliminate the remnant lesion, robot-assisted partial cystectomy was performed. The patient showed no evidence of recurrent disease on follow-up cystoscopy and computed tomography for up to 2 years. CONCLUSIONS: Clinicians should consider the possibility of eosinophilic cystitis in patients who present with hematuria, fever, and suprapubic pain and have both intravesical and extravesical masses.

Quiste de uraco complicado. Diagnóstico diferenciaI de abdomen agudo. Reporte de un caso / Cyst of urachus complicated. Differential diagnosis of abdomen acute. Case report

Reporte de caso: La literatura manifiesta que el quiste de uraco es raro, por lo cual el diagnóstico es aún más difícil de establecer, debido a que solo se presentan síntomas cuando ya existe una complicación, por tanto se puede suponer que algunas personas sean poseedoras de un quiste de uraco y sin presentar sintomatología, siguen con sus actividades de la vida sin problemas. A continuación, presentamos el caso de una paciente, que ingreso con una clínica sugerente de abdomen agudo por apendicitis, pero los exámenes de imágenes revelaron otro diagnóstico, confirmándose con la intervención quirúrgica y posteriormente anatomía patológica. (AU)

Case report: The literature states that the urachus cyst is rare, so the diagnosis is even more difficult to establish, because symptoms only manifest when a complication already exists, so it can be assumed that many people have a urachus cyst, and without having symptoms, they continue with their life activities without problems. Next, we present the case of a patient, who admitted to a clinic suggestive of an acute abdomen due to appendicitis, but the imaging tests revealed another diagnosis, confirming with the surgical intervention and subsequently pathological anatomy.

An infected urachal cyst presenting as acute abdominal pain in a child: A case report.

INTRODUCTION: Urachal cyst is an exceptionally rare disease in children caused by the incomplete obliteration of the urachal remnant. Urachal cysts seldom cause symptoms unless a secondary infection occurs. The symptoms of an infected urachal cyst are nonspecific and may be similar to acute appendicitis or other acute abdominal conditions. However, complications attributable to a delayed diagnosis can endanger the life of a patient. PATIENT CONCERNS: A 5-year-old boy presented with a 3-day history of severe intermittent lower abdominal pain. DIAGNOSIS: Infected urachal cyst. INTERVENTIONS: The patient was treated with surgical resection of the urachus, followed by intravenous antibiotics during the hospitalization. OUTCOMES: The patient was discharged without incident 7 days after the operation. With his follow-up in our out-patient department, he recovered well without any sequelae in the 6 months post-surgery. CONCLUSION: We suggested using the abdominal echo scan to differentiate the urachal cyst because of its high sensitivity and nonradioactive characteristic, and computed tomography is a typical diagnostic tool for urachal cysts. The mainstream management of an infected urachal cyst remains surgical excision. Complete excision of urachal cysts is relatively easy in a pediatric patient and the risk of subsequent infection is low; however, patients tend to have a low, although possible, risk of potential malignant transformation over their lifetimes.

[A man with abdominal pain and pollakisuria]. / Een man met buikpijn en pollakisurie.

An 18-year-old male presented in the emergency department with abdominal pain since two days and complaints of pollakisuria. Laboratory results showed increased infection parameters and ultrasound revealed an abscess in the abdominal lower right quadrant. The patient underwent diagnostic laparoscopy. We found an infected cyst, most likely an infected urachal remnant considering its location and the histological findings in the resected tissue.

Urachal Remnants in Patients Presenting to the Emergency Department with Abdominal Pain.

BACKGROUND: Rare causes of abdominal pain include abnormalities of the urachus, including patent urachus and urachal cyst with or without infection. However, reviews discussing etiology of abdominal pain, even in children, may completely omit mention of urachal remnants. OBJECTIVES: Determine the incidence of symptomatic urachal remnants in patients presenting to the emergency department (ED), including common presenting findings and method of diagnosis. METHODS: A retrospective chart review was performed of all patients presenting to the ED with abdominal pain who were diagnosed with urachal remnants, including patent urachus or urachal cyst or abscess over a period of 11 years and 7 months in one hospital. RESULTS: There were a total of 833,317 ED visits over the time period of the chart review, with 76,954 patients or 9.2% presenting with a complaint of abdominal pain. Twenty-four patients were identified, or 0.03% of those presenting with abdominal pain. Ages ranged from 16 days to 59 years. Among those 18 years or older, there was a male-to-female ratio of 1:1 of 14 patients. Thirteen patients (54.2%) initially presented with drainage from the umbilicus. CONCLUSIONS: Although rare, symptomatic disorders of urachal remnants may present at any age. These disorders should be kept in mind by the emergency physician among the broad list of differential diagnoses accounting for abdominal pain. Urachal cyst and abscess may present with or without drainage from the umbilicus. Drainage from the umbilicus is highly suggestive, but not pathognomonic, of a urachal anomaly, and patients should be imaged to make a definite diagnosis and assist in the management plan.

Prolapsed bladder following rupture of patent urachal cyst, mimicking bladder exstrophy: a case report and literature review.

A 26-year-old pregnant woman was diagnosed with fetal bladder prolapse following rupture of a patent urachus/urachal cyst, based on the finding of cyst disappearance with replacement with an infra-umbilical, extra-abdominal solid soft-tissue mass, mimicking bladder exstrophy. The neonatal findings confirmed the prenatal diagnosis. The baby was healthy and had a successful surgical correction. This report provides clues to differentiating ruptured bladder prolapse from bladder exstrophy as follows: (1) well-documented urachal cyst with urine-filled mass in the early gestation, (2) development of solid soft-tissue mass shortly after disappearance of the urachal cyst, and (3) no other structural abnormalities (bladder exstrophy is usually associated with abnormal genitalia, epispadias, or pubic diastasis). This study underlines the differentiation between the two entities because of the vast difference in prognosis, management, and proper counseling.

[Delayed umbilical cord separation]. / Een prematuur met een niet indrogende navelstomp.

We present the case report of a preterm infant with delayed umbilical cord separation. At the age of four weeks the umbilical cord separation had still not occurred. The umbilical cord tissue sometimes seemed wet and did not dry completely. There were no signs of immunodeficiency. An ultrasound of the abdomen showed a small urachal cyst. No further intervention was indicated.

A Rare Urachal Cyst in a Case of Ketamine-induced Cystitis Provides Mechanistic Insights.

OBJECTIVE: To establish whether the urothelial ulceration observed in ketamine-induced cystitis is triggered by urinary or systemic factors. This was achieved with a rare case where an urachal cyst was found near the bladder dome in a patient undergoing cystectomy for unremitting pain following ketamine abuse. METHODS: Clinical investigations included cystoscopy, video urodynamic investigation, and computed tomography of the kidneys, ureters, and bladder. Histological staining was combined with immunoperoxidase labeling for markers of transitional epithelial differentiation. RESULTS: The urachus found near the dome of the bladder was observed to be a separate cyst, with no evidence of patency found during surgery or video urodynamic investigation. The urachus was lined by a mildly reactive metaplastic epithelium of mixed transitional and columnar morphologies. Evidence of widespread cytokeratin 13, basal p75(NTR), and sparse superficial uroplakin 3a immunoreactivity suggested the urachal epithelium was fundamentally transitional in nature. Near total loss of bladder urothelium was observed from regions in contact with urine, whereas the urachal epithelium (not exposed to urine) remained healthy. CONCLUSION: This study supports the hypothesis that urinary (and not systemic) factors are the main driver of urothelial ulceration in ketamine-induced cystitis. The most likely excreted factors responsible are ketamine and potentially its metabolites. This study reinforces the importance of complete cessation of ketamine use in patients with ketamine-induced cystitis.
