Infected urachal cyst initially misdiagnosed as an incarcerated umbilical hernia

A Rare Case of Urachal Cyst in a Patient With Uterine Fibroids

A 41-year-old woman presented to the emergency department with pain in her abdomen during menstruation. On examination, we detected a cystic lump in the midline, just below the umbilicus. Ultrasonography of the whole abdomen was suggestive of uterine fibroids with a probable mesenteric cyst. Computed tomography of the abdomen confirmed an otherwise asymptomatic, silent, urachal cyst connected to the umbilicus and urinary bladder by obliterated bands. The cyst was explored and removed surgically under combined spinal-epidural anesthesia, following a single-staged approach. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was subsequently performed. Urachal cysts are rare congenital anomalies. Any unexpected finding on clinical examination should alert clinicians for further evaluation and treatment.

Acute Presentation of Urachal Cyst: A Case Report

Urachus is an embryonic organ related to the bladder that degenerates after birth. Defective obliteration of the urachus leads to urachal malformations, the most common of which is a urachal cyst. A urachal cyst is often misdiagnosed due to its myriad presentations. Delay in diagnosis can lead to complications such as sepsis, fistula formation, and rupture of the cyst mimicking peritonitis. Hence, a high index of suspicion is required for the timely diagnosis and management of urachal cysts presenting in the emergency room. We report the case of a 32-year-old woman who presented with clinical features suggestive of an acute abdomen. The judicious use of imaging confirmed the diagnosis of an infected urachal cyst, which was surgically managed.

Surgical management for an infected urachal cyst in an adult: Case report and literature review

INTRODUCTION

Incomplete urachal obliteration during fetal development gives rise to distinct malformations of the median umbilical ligament. Most anomalies are asymptomatic and resolve during early infancy, but some go unrecognized until adulthood. These rare cases can present with acute abdominal symptomatology secondary to infected urachal remnants.

PRESENTATION OF CASE

A 20-year-old man presented with periumbilical pain. Physical exam showed a warm, erythematous infra-umbilical mass that was tender to palpation. CT revealed an infected urachal cyst. The patient underwent urachal abscess incision and drainage with cyst excision. The patient returned home on postoperative day two. Two-week outpatient follow-up confirmed an uncomplicated recovery.

DISCUSSION

Surgical excision of urachal anomalies in adults is curative and preventive against recurrent infection and malignancy, but preoperative management is currently unstandardized. Current literature recommends a two-stage approach characterized by preoperative antibiotics and cyst incision and drainage followed later by complete surgical excision. Our patient underwent a single therapeutic approach with preoperative antibiotics and definitive operative excision. Our patient had a comparable outcome with no complications and a short hospitalization.

CONCLUSION

Preoperative antibiotics with excision of urachal remnants was effective in our case. Staged approaches are appropriate in complicated cases as a means to reduce post-operative infection rates and hospital stays. Urachal remnant excision is recommended in adults to prevent future malignancy.

Laparoscopic treatment of an infected urachalcyst and diverticulum in a young adult: Presentation of a case and review of the literature

INTRODUCTION

A urachal remnant is a rare anomaly in adults, with a heterogeneous presentation. We report a case of an infected urachal cyst associated with a urachal diverticulum.

PRESENTATION OF CASE

We report the case of a 16-year-old male who presented to our hospital with lower abdominal pain without any other signs of general infection. A physical examination revealed umbilical erythema with associated tenderness. All laboratory tests were normal. An ultrasound scan revealed an urachal cyst near the umbilicus and a second cyst near the bladder dome. We decided on a staged treatment with antibiotic administration followed by surgical excision of the urachus during laparoscopy. The patient was discharged on day 10 without complications. Pathology revealed chronic inflammatory tissue without signs of malignancy.

DISCUSSION

Urachus is a fibrous remnant of the allantois that progressively obliterates after birth, forming the median umbilical ligament. Incomplete regression of the urachal lumen results in several anomalies. These anomalies require treatment when discovered because of an increased risk of infection and neoplastic differentiation. A urachal cyst is the most common type of anomaly, and infection is the usual mode of presentation. Surgical intervention with complete excision of the urachus is the treatment of choice. A staged approach with antibiotic administration followed by surgery is recommended if signs of infection are present.

CONCLUSION

Urachal anomalies in adulthood are rare, with a nonspecific presentation. However, identifying a urachal anomaly is important because of the increased risk for infection and neoplastic differentiation. The laparoscopic approach is safe and patients recover rapidly.

Urachal Cyst Causing Small Bowel Obstruction in an Adult with a Virgin Abdomen

Introduction. A patent urachus is a rare congenital or acquired pathology, which can lead to complications later in life. We describe a case of urachal cystitis as the etiology of small bowel obstruction in an adult without prior intra-abdominal surgery. Case Report. A 64-year-old male presented to the acute care surgery team with a 5-day history of right lower quadrant abdominal pain, distention, nausea, and vomiting. He had a two-month history of urinary retention and his past medical history was significant for benign prostate hyperplasia. On exam, he had evidence of small bowel obstruction. Computed tomography revealed high-grade small bowel obstruction secondary to presumed ruptured appendicitis. In the operating room, an infected urachal cyst was identified with adhesions to the proximal ileum. After lysis of adhesions and resection of the cyst, the patient was subsequently discharged without further issues. Conclusion. Although rare, urachal pathology should be considered in the differential diagnosis when evaluating a patient with small bowel obstruction without prior intraabdominal surgery, hernia, or malignancy.

Lesions of the umbilicus: what the minimally invasive gynecologic surgeon needs to know about the belly button

The umbilicus is viewed as a portal by the laparoscopic surgeon, a doorway to the real business at hand. However, the umbilicus itself may be the site of a variety of lesional conditions. Some of these may be iatrogenic, caused by prior surgical interventions, such as endometriosis or seeding of a malignant neoplasm. Some may be the initial presenting complaint. This review discusses umbilical lesions that may be encountered by the minimally invasive gynecologic surgeon.

An infected urachal cyst presenting as an acute abdomen - A case report

INTRODUCTION

An infected urachal cyst is one of a spectrum of presentations of urachal pathology, all of which are rare in adulthood.

PRESENTATION OF CASE

We report the case of a 45-year-old obese Russian lady who presented with a 2-week history of suprapubic pain radiating to the right iliac fossa. Although previously fit and well, she had a history of 17 miscarriages. Both USS and CT suggested a complicated inflammatory mass in the lower abdomen. Ultimately the diagnosis was made by laparotomy, which revealed an abscess of an urachal cyst. The infected cyst and bladder dome were excised. The patient made a good recovery with an uneventful follow up.

DISCUSSION

Urachal cysts are the commonest type of urachal anomaly. Infection is the usual mode of presentation amongst adult cases otherwise the condition usually remains asymptomatic. An infected urachal cyst is an important diagnosis to make as complications include sepsis, fistula formation, and rupture leading to peritonitis. Treatment is by complete excision, however, techniques have been debated.

CONCLUSION

This is a rare but important diagnosis however we recommend that in patients with atypical histories, it should be included in the differential diagnosis.

Abscess of urachal remnants presenting with acute abdomen: a case series

Introduction

Urachal diseases are rare and may develop from a congenital anomaly in which a persistent or partial reopening of the fetal communication between the bladder and the umbilicus persists. The most frequently reported urachal anomalies in adults are infected urachal cyst and urachal carcinoma. The diagnosis of this entity is not always easy because of the rarity of these diseases and the atypical symptoms at presentation. Imaging techniques, such as ultrasonography and computed tomography have a significant role in recognizing the presence of urachus-derived lesions.

Cases presentations

Case presentation 1: A 25-year-old Arab-Berber man presented with a 10-day history of progressive lower abdominal pain accompanied by fever, vomiting, and low urinary tract symptoms to our emergency department. Laboratory data revealed leucocytosis. The diagnosis of an acute peritonitis was made initially. Abdominal ultrasonography revealed a hypoechoic tract from the umbilicus to the abdominal wall, and the diagnosis was rectified (infected urachal remnants). The patient was initially treated with intravenous antibiotics in combination with a percutaneous drainage. Afterwards an extraperitoneal excision of the urachal remnant including a cuff of bladder was performed. The histological analysis did not reveal a tumor of the urachal remnant. Follow-up examinations a few months later showed no abnormality.

Case presentation 2: A 35-year-old Arab-Berber man, without prior medical history with one week of abdominal pain, nausea and vomiting, associated with fever but without lower urinary tract symptoms visited our emergency department. Laboratory data revealed leucocytosis. Abdominal ultrasonography was not conclusive. Computed tomography of the abdomen was the key to the investigation and the diagnosis of an abscess of urachal remnants was made. The patient underwent the same choice of medical-surgical treatment as previously described for case one, with a good follow-up result.

Case presentation 3: A 22-year-old Arab-Berber man, with no relevant past medical history, presented to our emergency department because of suspected acute surgical abdomen. Physical examination revealed umbilical discharge with erythema and a tender umbilical mass. Abdominal ultrasonography and computed tomography scan confirmed the diagnosis of infected urachal sinus. Initial management was intravenous antibiotics associated with a percutaneous drainage with a good post-operative result, but a few days later, he was readmitted with the same complaint and the decision was made for surgical treatment consisting of excision of the infected urachal sinus. The clinical course was uneventful. Histological examination did not reveal any signs of malignancy.

Conclusions

We describe our clinical observations and an analysis of the existing literature to present the various clinical, radiological, pathological and therapeutic aspects of an abscess of urachal remnants. To the best of our knowledge, this manuscript is an original case report because this atypical presentation is rarely reported in the literature and only a few cases have been described.
