We report four cases who were referred to Mansoura University Teaching Hospital, Egypt suffering from abdominal pain and gastrointestinal manifestations. The patients' history was unremarkable, except that they had contact with dogs and live in rural communities. Laboratory findings showed peripheral blood eosinophilia, leucocytosis, and elevated liver enzymes. Serological tests were positive in three cases. Ultrasonography showed well-circumscribed cystic masses in the liver. Diagnosis of hydatid cysts was confirmed by computed tomography (CT). Surgical treatment along with chemotherapy was performed and all patients recovered well. The results of these cases support the notion that CT scan can led to increased clarity, regarding surgical management, because of discordance between radiographic and laboratory findings.
