Isolated Prostatic Hydatid Cyst: A Case Report

Hydatid cystic disease is caused by Echinococcus granulosus, a parasite that infects humans and might not spare any organ but the cornea; nevertheless, its occurrence in the pelvis or prostate is extremely rare, with only a few reported cases. We report the case of a 25-year-old gentleman, medically and surgically free, with a negative personal or family history of hydatid cystic disease, who presented to urology clinics with progressive obstructive lower urinary tract symptoms and one episode of urine retention. Pelvic MRI and CT revealed a well-defined cystic lesion in the left prostatic lobe, initially interpreted as a simple cyst. Transurethral deroofing, performed in August 2022 at Prince Hussein Urology Center/Jordanian Royal Medical Services, revealed whitish membranous material suggestive of a hydatid cyst, which was completely evacuated. The postoperative course was uneventful, and there was no other organ involvement upon investigation. Histopathologic study of the cyst showed it to be a hydatid cyst. He was followed up for 24 months with no evidence of local or systemic recurrence and was symptom-free throughout. Isolated prostatic hydatid cysts are extremely uncommon and easily misdiagnosed. In endemic regions, awareness of this entity and careful perioperative assessment are essential for accurate diagnosis. Complete endoscopic evacuation with scolicidal irrigation shows favorable outcomes and can prevent recurrence. In endemic areas, prostatic cystic lesions should raise suspicion for hydatid disease to properly map patients' management. Moreover, intraoperative suspicion is paramount for definitive diagnosis and successful management.
