Primary Retroperitoneal Hydatid Cyst: A Diagnostic and Treatment Conundrum

Cureus. 2024 Feb 8;16(2):e53842. doi: 10.7759/cureus.53842. eCollection 2024 Feb.

Abstract

Hydatid cysts are caused by accidental egg ingestion of the Echinococcus granulosus parasite. A 24-year-old female was admitted to our hospital for chronic left lumbar pain. Computed tomography (CT) and abdominal ultrasonography identified an 8/12 cm retroperitoneal cyst. The CT results coupled with enzyme-linked immunosorbent assay tests (positive IgG for Echinococcus granulosus) confirmed that the tumor was a hydatid cyst. Treatment consisted of preoperative chemotherapy with albendazole, intraoperative parasite inactivation, laparoscopic partial cystectomy, and drainage. The drain was removed after three days. Chemotherapy was maintained for two years after surgery. No relapse was observed at the six-month reevaluation. In this article, the diagnostic and therapeutic options and resources are discussed and compared with the published literature.
