Hydatid cyst disease is an important health problem in many countries, including Turkey. While it can impact any organ, it is most often found in the lung and liver. Renal involvement is relatively rare. A diagnosis of renal cystic hydatidosis was established with ultrasound and magnetic resonance in a 22 year old patient who was 25 weeks pregnant after she presented with severe right flank pain. Albendazol was administered at a dose of 10 mg/kg/day. She was closely followed during her pregnancy. At 38 weeks, she gave birth to a healthy baby via vaginal delivery. Following her delivery, the cyst was resected. Post-operatively, she completed an 8 week course of albendazol at a dose of 10 mg/kg/day. 1 year later, the patient has done well with no complications. We presented this case to highlight the lack of consensus in regards to the treatment of renal hydatid cyst disease in pregnancy.
