How to tell if Cholangiocarcinoma is an intrahepatic tumor?
For an intrahepatic mass-forming cholangiocarcinoma consider: 1 liver metastases central necrosis (high T2 signal) is more common 2 hepatocellular carcinoma (HCC) tumor thrombus more common capsular retraction uncommon may appear very similar 3 other primary liver tumors 4 hepatic abscess
What kind of MRI is used for cholangiocarcinoma?
Materials and methods: Fifty-four patients with histologically proven intrahepatic cholangiocarcinoma underwent MRI of the liver using a 1.5T MR-scanner with Gadoxetic acid disodium (Gd-EOB-DTPA; Eovist/Primovist, Bayer Healthcare, Berlin, Germany).
Which is the mass forming form of cholangiocarcinoma?
Mass-forming intrahepatic cholangiocarcinomas (MF-ICC), also referred as peripheral cholangiocarcinomas, comprise one of the three recognized growth patterns of intrahepatic cholangiocarcinomas .
Can a central scar be a marker for cholangiocarcinoma?
Some investigators have reported that the central scar displayed on MR images in cholangiocarcinoma can be a reliable marker, allowing cholangiocarcinoma to be distinguished from metastatic liver tumors [ 7, 8, 9] because central scars are not typically observed in the latter [ 16 ].
Which is the most common type of cholangiocellular carcinoma?
Cholangiocellular carcinoma (CCC) is usually classed as “intrahepatic” or “extrahepatic” depending on the site of origin. Intrahepatic cholangio-carcinoma (ICC) is a malignant neoplasm arising from the epithelium of the intrahepatic bile ducts and represents approximately 10% of all CCC.
What kind of mass is found in cholangiocarcinoma?
At computed tomography (CT), mass-forming intrahepatic cholangiocarcinoma usually appears as a homogeneous low-attenuation mass with irregular peripheral enhancement and can be accompanied by capsular retraction, satellite nodules, and peripheral intrahepatic duct dilatation.
