Juxtavesical hydatid cysts

Area of Science:

• Urology
• Parasitology
• Radiology

Background:

• Hydatid disease, caused by Echinococcus granulosus, typically affects organs like the liver and lungs.
• Juxtavesical (near the bladder) hydatid cyst localization is an uncommon presentation of this parasitic infection.

Purpose of the Study:

• To describe the clinical characteristics, diagnostic challenges, and management of juxtavesical hydatid cysts.
• To highlight the importance of considering parasitic etiologies in pelvic masses.

Main Methods:

• Retrospective review of 9 cases with juxtavesical hydatid cysts out of 177 total hydatid localizations.
• Diagnosis involved clinical examination, radiological imaging (e.g., ultrasound, CT), and surgical exploration.
• Patient history and co-existing parasitic lesions aided diagnosis.

Main Results:

• Nine juxtavesical hydatid cysts were identified among 177 hydatid localizations.
• Three patients presented with recurrent cysts.
• Diagnostic difficulties arose due to co-existing pathologies or cyst characteristics mimicking malignancy.
• One case of severe late renal complication was noted.
• Seven patients were treated surgically.

Conclusions:

• Juxtavesical hydatid cysts, though rare, require a high index of suspicion for diagnosis.
• Differential diagnosis should include parasitic cysts, especially in endemic areas.
• Prompt surgical intervention is crucial for managing symptomatic and recurrent juxtavesical hydatid disease.
