Background: Hydatid cyst (HC) represents a remarkable zoonotic parasitic disease, mostly affecting the liver and lungs. In this report, we present a patient from northern Iran who exhibited HC involvement in the pelvic region, a rare occurrence that is often asymptomatic.
Case presentation: A 41-year-old female presented with hypogastric pain, and imaging survey showed the potential presence of cystadenoma, endometriosis, and various typical ovarian lesions. She underwent laparotomy, during which pelvic HC was identified. Serological testing confirmed this finding. Also, albendazole was prescribed, and she was discharged in relatively good condition.
Conclusion: In regions where this infection is prevalent, HC must be considered in the differential diagnosis of ambiguous cystic tumors. This case highlights the importance of including HC in the differential diagnosis of pelvic cysts, especially in endemic areas. Furthermore, we recommend the using of molecular techniques during surgical interventions as potentially beneficial.
