A 28-year-old lama, who came from Nepal, presented with intermittent abdominal pain for 2 years. Abdominal sonography, CT and MRI showed a multiloculated cystic mass in the caudate lobe of liver with some punctate calcifications at the peripheral wall and thickened septa. Under the impression of hepatic hydatid cyst, the patient received left lobectomy and cholecystectomy. Histological study of the lesion showed a cyst with many daughter cysts lying free in the cyst fluid. Hydatid cyst is uncommon in Taiwan and has been found only in immigrants or persons with a history of travel to endemic areas. It may be asymptomatic or may lead to lethal complications. Surgery is considered the optimal treatment that has the potential to remove the cyst and leads to complete cure. It is important to make a preoperative diagnosis based on the typical image findings, so that surgeons may take particular precaution not to rupture the lesion as peritoneal spillage may lead to disseminated implantation.
