48-year-old male underwent laparoscopic cholecystectomy for symptomatic cholelithiasis. During post-surgery he developed intense abdominal colics and a situation of hepatitis, probably from medicines as the tests carried out. Performed tests revealed changes of haematic values related to the hepato-renal function. MR-cholangiography showed cystic formation in the right lobe of the liver, and tumor markers that gave evidence of an increase of alpha-fetoprotein which should be monitored.
