[Caroli's syndrom in ultrasound and CT (author's transl)].

Until a few years ago diagnosis of congenital saccular intrahepatic dilatation of bile ducts (Caroli's syndrome) was established intraoperatively or postmortem only. Intravenous cholangiocholecystography and intraoperative cholangiography will often furnish insufficient information. Preoperative diagnosis has become possible for some time now via percutaneous transhepatic and endoscopic retrograde cholangiography. Basing on a case history it is shown that non-invasive diagnosis of Caroli's syndrome has now become possible without the risk of a possible life-threatening cholangitis relapse. This is the merit of new techniques such as sonography and computerized tomography.
