Retrovesical hydatic cyst: About 4 cases

Large seminal vesicle hydatid cyst in a young male: A case report with technical modification approach

INTRODUCTION

Hydatid disease (HD) rarely affects the genitourinary system, comprising only 2-4 % of all hydatid infections. While kidney involvement is more common, seminal vesicle HD is rarely reported.

CASE PRESENTATION

We describe a 39-year-old man with an incidentally found large pelvic hydatid cyst arising from the seminal vesicle. Despite adhesion to adjacent organs, we successfully drained the cyst content through a small hole of the cyst wall in a sterile setting. The patient remained symptom-free, maintained potency and urinary continence and the lesion decreased in size, significantly after six-month follow-up.

DISCUSSION

Surgical excision remains the preferred treatment for seminal vesicle hydatid disease (HD). During surgery, extreme caution must be exercised to prevent cyst rupture or irritation of adjacent organs. While complete excision is ideal, in cases where the cyst adheres to adjacent organs, partial cystectomy or cyst drainage should be considered.

CONCLUSION

Cyst drainage proves effective, especially in cases of adjacent organ invasion.

Pelvic hydatid cyst revealed by acute retention of urine: A case report

We report the rare case of a primary pelvic hydatid cyst in a 37-years old from a rural area. The diagnosis was suspected preoperatively based on the origin of the patient, and CT findings and it was confirmed intraoperatively by finding the typical cystic content. A total excision of the cyst without causing or contamination of the field was carried out by median incision. Our work aims to point to an unusual localization of hydatid disease, clinical and radiological characteristics, and above all to discuss the different ethnic-pathogenic theories and surgical treatment.

Retrovesical hydatid cyst: an unusual location of hydatid disease about a case series

Hydatid disease is an endemic zoonosis in regions with temperate climates where pastoral farming is common. Retrovesical localization is rare. Given the rarity of this entity, the lack of personal clinical experience, and the difficulty with detecting early symptoms, the diagnosis remains elusive for years.

Methods

This is a 30-year retrospective, descriptive and analytic study of seven patients who were hospitalized and operated on in the Department of Urology during 30 years (1990-2019).

Outcomes

The average patient age was 54 years (range: 28-76). Signs of bladder irritation were the predominant presenting complaint. No cases of hydaturia were noted. Preoperative diagnosis was based on ultrasonography and serology tests. Hydatid serology was positive for three patients. In three cases, a hydatid cyst of the liver was associated. A partial cystopericystectomy was performed for five patients, it was total for one patient. The resection of the prominent dome was realized once. No cystovesical fistula was found. The mean postoperative stay was 16 days. The postoperative course was uneventful for five patients. Urinary fistula occurred in one patient. One case of infection of the residual cavity was observed. One patient had a retroperitoneal cyst recurrence requiring reoperation.

Conclusion

The preoperative diagnosis of retrovesical hydatid cysts is based mainly on ultrasonography. Open surgery is the treatment of choice. Different approaches are possible. Given the rarity of this entity, management should be guided by experienced experts.

Diagnosis of Primary Hydatid Cyst of Thyroid Gland: A Case Report

A 34-year-old female patient was presented to the general surgery clinic of the hospital complaining of a growing tangible swelling in her neck. In physical examination, the patient had two palpable soft nodules in the left lobe of the thyroid which hadn't invaded the surrounding tissues. The function of thyroid gland was normal and fine needle aspiration (FNA) result reported it benign. The patient went through a left lobectomy and isthmectomy. The histopathology report concluded a nodular hyperplasia and a Hydatid cyst. After surgery, the patient was examined searching for any other organs cyst, but there were no cystic lesion in the cranial, thoracic and abdominal cavities. Accordingly, the case was a primary thyroid hydatid cyst, which is rare, even in endemic regions like Iran.

Multiple unusual urological locations of hydatic cysts including kidney, retrovesical and spermatic cord. A new case report

Human hydatidosis is endemic in regions with temperate climate where pastoral farming is common.

It is frequent in the southern shore of the Mediterranean, particularly in the Maghreb countries. It remains asymptomatic for long period, and the diagnosis is often delayed. The most affected organs are the liver and lungs. Hydatic disease of the urinary tract is an unusual entity.

Our case concerns multiple unusual locations of hydatic disease in the urinary tract, including renal, retrovesical and spermatic cord, associated with splenic and intraperitoneal locations. Coexistence of hydatic cysts in such locations of urinary tract has not been previously reported.

An undiagnosed giant right renal hydatid cyst treated laparoscopically: Case report and review of literature

Hydatid disease caused by the tape worm Echinococcus granulosus is a rare occurrence in the urinary system in general. We are hereby presenting a case of a gentleman in his fourth decade with a giant right renal hydatid cyst. The clinical manifestations, radiological features, and serology were all not suggestive of hydatid disease; however, typical Echinococcus scolices were detected histologically following cyst aspiration. The giant cyst was successfully treated laparoscopically.
