Rationale: Cystic echinococcosis (CE) is a parasitic zoonosis caused by echinococcus larvae. Manifestations of the disease include a severe damage to the liver and lung. Damages to the mesentery, omentum, spleen, brain, heart, bone, thyroid, kidney, and uterus are rarely observed. Moreover, primary ovarian and retroperitoneal hydatid disease is extremely rare, and is easily ignored or misdiagnosed.
Patient concerns: We present a case of CE in a 34-year-old female who presented with an adnexal mass detected by B-ultrasound. Adnexal and retroperitoneal masses were removed by laparoscopic surgery. Postoperative pathological report (retroperitoneal cyst) Echinococcus granulosus.
Diagnoses: Primary ovarian and retroperitoneal hydatid disease.
Interventions: The patient received intravenous injection of dexamethasone (10 mg) before cyst resection to prevent allergic reactions and oral albendazole (600 mg BID) for 14 days to prevent relapse postsurgery.
Outcomes: The patient revealed no recurrence of disease and no reportable significant changes in 3 months.
Lessons: We present here a case report of CE. This case described herein inhabited a nonendemic region. Gentle and careful operation, and avoiding cyst rupture is the key to insuring success of the surgery. For safety, dexamethasone may be used before cyst resection to prevent anaphylaxis, and mebendazole can be used postoperatively to prevent relapse.
