Abstract:
Objective To evaluate the dynamic MR imaging findings of peripheral cholangiocarcinoma (PCC) of the liver. Methods Seventeen patients with PCC underwent dynamic MRI during the early, middle, and delayed phase after contrast medium administration. Enhancement pattern of the tumor, the wedge-like enhancement area peripheral to the tumor, dilatation of the intrahepatic biliary ducts, vascular involvement, and extrahepatic tumor invasion were evaluated. Results Early peripheral enhancement with progressive and concentric filling by contrast medium was the most frequent enhancement pattern (9 patients). A wedge-like enhancement area was observed in 10 patients. Ductal dilatation was found in 11 patients. Vascular involvement and extrahepatic invasion were seen in 8 and 2 patients, respectively. Conclusion Enhancement pattern is relative to the character of pathology (quantity and distribution of cell and fibrosis). Early peripheral enhancement with progressive and concentric filling by contrast medium may be specific for PCC.
