[Liver hydatidosis in an eight-year-old child]

The first pediatric case of hepatic hydatidosis diagnosed in Mexico is reported. Previous to surgery, the diagnosis was established, based on a cystic tumor of the liver, the X ray findings, defects in the liver uptake, eosinophilia and Casoni's positive intradermal reaction. Besides, the immunoelectrophoresis test showed specific antibodies. Clinical and epidemiological considerations, related with the pathology and treatment of hydatidic disease are made, stressing the importance to know the symtoms of the illness, in order to establish the diagnosis and treatment. Likewise, the prognosis is evaluated considering the remaining cysts of the liver and the possible seeding of the parasite into the peritoneal cavity. Pertinent literature on the subject is reviewed.
