Abstract
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.
