[Hepatic incidentaloma. A case report of cholangiocarcinoma].

The finding of incidentalomas is becoming increasingly frequent during the course of routine diagnostic tests. At the hepatic level, the preclinical diagnosis of primary tumours has enabled a growing number of patients to undergo surgery with reduced operating trauma and greater oncological radicality. The authors report a case of cholangiocarcinoma whose pre-clinical diagnosis enabled its resection in spite of the patient's advanced age.
