Abstract
Introduction: Hydatid disease (HD) is an infestation caused by the larval stage of Echinococcus granulosus. It can be seen in any part of the body, but the liver is the most common site. Retroperitoneal HD is rare, and an isolated retroperitoneal hydatid cyst is extremely rare. Diagnosis of hydatid cyst at unusual locations & with varied imaging appearances is challenging.
Case Presentation: A 24yrs old lactating female came to gynecology OPD for tubectomy. She was asymptomatic. On examination, palpable mass is noted & was advised USG abdomen. On USG revealed a large lobulated thick-walled cystic lesion with layered turbid collection within it, in left adnexa, and CECT abdomen is suggestive of retroperitoneal hydatid cyst/ cystic neoplasm. PAIR technique was done for the larger cyst & the rest of the collection with few small cysts was sent to the pathological examination.
Discussion: Cysts in the peritoneum/retroperitoneum are mainly due to spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Total cystectomy was considered as the gold standard treatment & Albendazole, or praziquantel is indicated for inoperable and disseminated cases. PAIR technique is a nonsurgical option.
Conclusion: In an endemic region of hydatid disease, retroperitoneal hydatid cyst should be considered as one of the differential diagnosis, when one encounters cystic retroperitoneal mass.
