Large solitary paravaginal hydatid cyst: a rare cause of urethral injury

Hydatid cyst is a parasitic infectious disease caused by Echinococcus granulosus . Although the most common site for this parasite is liver, it can be seen in almost all organs. Extrahepatic localization is reported in 14–19% of all cases of abdominal hydatid disease. We report the case of a large echinococcal cyst localized in the paravaginal area in the lower pelvis. A 43-year-old woman was admitted to our gynecology clinic for pelvic discomfort and dyspareunia. During her physical examination, a paravaginal cystic mass was found. Ultrasonography and magnetic resonance imaging revealed a large paravaginal cystic mass. During cyst wall dissection, distorted and fibrotic distal urethra was injured. End-to-end urethroplasty was performed. She had urinary continence after the surgery. Pathology revealed the diagnosis of echinococcosis. Antihelmintics were administered postoperatively, and the patient was discharged after day 7 uneventfully and has been under follow-up for 1 year.
