the cystic hepatic mesenchymal hamartoma in an adult mistaken for hydatid disease: case report

Hydatid cyst is one of the predominantly cystic liver lesions and is also a zoonotic disease that is highly endemic in the mediterranean region. this condition has extensive differential diagnoses, such as hepatic mesenchymal hamartoma, a rare benign hepatic tumor, which commonly occurs in infants and children, and is extremely rare in adults. its imaging findings vary from a cystic tumor to a solid mass occupying one or both lobes of the liver. we report an unusual case of a purely cystic mesenchymal hamartoma of the liver in a 60-year-old female patient. the patient had been treated with albendazole for several years; however, the final histopathology revealed mesenchymal hamartoma.
