“…Therefore, capsular retraction in association with a peripheral hepatic mass should be considered as highly suggestive for epithelioid hemangioendothelioma of the liver. In accordance with a recent study [15], our two cases reaffirm that retraction of the liver capsule adjacent to an hepatic tumor is not a specific finding for epithelioid hemangioendothelioma of the liver but can be associated with other malignant hepatic tumors, particularly, intrahepatic cholangiocarcinoma.…”

“…Capsular retraction is an imaging feature originally described on CT that is not only associated with cholangiocarcinomas but a variety of other malignant hepatic tumors. In the setting (42). Dilated biliary ducts with intraductal stones may be found distal to the mass (40).…”

Intrahepatic cholangiocarcinomas account for approximately 20% of cases of cholangiocarcinomas.Three growth patterns or morphologic subtypes exist, including mass-forming, periductal-infiltrating, and intraductal-growth subtypes. Knowledge of these morphologic subtypes and their radiologic appearance aids in timely diagnosis, a key to optimizing patient outcomes. The morphologic variability of intrahepatic cholangiocarcinomas has a direct impact on the diagnostic sensitivity and specificity of various diagnostic imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET).The following review emphasizes optimal imaging technique for each of these modalities and reviews the imaging appearance of each morphologic subtype of intrahepatic cholangiocarcinoma.

“…We reported 8 cases (27%) with segmental or lobar atrophy, in which all patients but two showed portal vein branches or hepatic vein encasement or biliary duct obstruction. Capsular retraction was seen adjacent to the tumor in 18 cases (62%), though other malignant tumors also show capsular retraction [24]; the dense fibrotic nature of IMC may be the cause of retraction of the adjacent liver capsula.…”

Intrahepatic mass-forming cholangiocarcinoma: enhancement pattern on Gd-BOPTA-MRI with emphasis of hepatobiliary phase

et al. 2015

View full text Add to dashboard Cite

Gd-BOPTA MRI pattern of IMC on dynamic study is similar to that of conventional extracellular agents, that is peripheral enhancement with progressive and concentric filling of contrast material on delayed phases. At 10-15 min delayed phases, IMC shows often a peripheral hypointense rim consistent with a target appearance. In the HBP, due to progressive central enhancement (cloud) and peripheral hypointense rim, an higher number of tumors show a target appearance; this pattern is not specific and would also be expected to be seen in metastases from adenocarcinoma.
