Abstract
Pancreas is an uncommon site of hydatid cysts (HCs) even in endemic countries. Primary pancreatic hydatid cysts (PHCs) mainly occur through hematogenous dissemination. Their rarity and the absence of clinical manifestations in most cases explain their challenging preoperative diagnosis. In symptomatic cases, clinical findings may be similar to those of other diseases. We report a case of a 54-year-old female presented with a six-month history of abdominal pain, although her abdominal examination was normal. Radiological imaging revealed a serous cyst in the body and tail of the pancreas. Biliopancreatic endoscopic ultrasound (EUS) suggested a peritoneal hydatid cyst. Intraoperatively, it was diagnosed as a PHC. The patient underwent resection of the PHC and was then placed on albendazole. She did not have any symptoms for the last seven months. Through this case report, we can conclude that peritoneal hydatid cyst of the pancreas should be considered in the differential diagnosis of the cystic lesions of the pancreas. Moreover, surgery achieves a definitive treatment of the disease.
