Omental hydatid cysts usually secondarily exist after the spontaneous, traumatic, or iatrogenic perforation of primary abdominal hydatid cysts. An isolated omental hydatid cyst in the absence of other organ involvement is very rare. Here, we present a 49-year-old male with a primary omental hydatid cyst. He was living in an urban area, but he spent his childhood in rural areas and worked with livestock. The differential diagnosis was not easy because of the negative serological test. Laparoscopic exploration revealed the diagnosis of hydatid cyst and it was removed by laparoscopy without spillage of the cyst contents. After the total excision, no albendazole treatment was prescribed. Isolated omental hydatid cysts should be in the differential diagnosis of the peritoneal cysts and its laparoscopic total excision is a feasible treatment.
