AbstractBackground: The purpose of our study was to evaluate the imaging features and patterns of contrast enhancement in peripheral cholangiocarcinomas with computed tomography (CT) and correlate these features with histologic findings when available. Methods: We reviewed the CT scans of 24 patients with 25 peripheral cholangiocarcinomas proved by orthotopic liver transplantation (n= 1), liver resection (n= 7), percutaneous needle biopsy (n= 10), and fine needle aspiration biopsy (n= 6… Expand
Common CT findings of cholangiocarcinoma at King Chulalongkorn Memorial Hospital ( KCMH )
Background We evaluated CT findings of 45 patients with cholangiocarcinomas. Objective To evaluate CT findings and pattern enhancement of cholangiocarcinoma at King Chulalongkorn Memorial HospitalExpand
Intrahepatic peripheral cholangiocarcinoma (IPCC): comparison between perfusion ultrasound and CT imaging
TLDR
The perfusion patterns of intrahepatic peripheral cholangiocarcinoma (IPCC) on contrast-enhanced ultrasound (CEUS) and dynamic computed tomography (CT) are compared to show enhancement discrepancy between delayed-phase CEUS (hypoechogenicity) and CT (hyperdensity). Expand
Cholangiolocellular Carcinoma of the Liver: Imaging Findings
TLDR
Although CLC with dense central fibrosis exhibits imaging features similar to those exhibited by intrahepatic cholangiocarcinoma, early enhancement in most lesions with persistent delayed enhancement is one of the characteristic imaging findings of this rare tumor. Expand
Intrahepatic mass-forming cholangiocarcinomas: enhancement patterns at multiphasic CT, with special emphasis on arterial enhancement pattern--correlation with clinicopathologic findings.
TLDR
Arterial enhancement of IMCCs was found to be an independent prognostic factor for longer disease-free survival and appears to correlate with disease- free survival. Expand
Intrahepatic cholangiocarcinoma: relationship between tumor imaging enhancement by measuring attenuation and clinicopathologic characteristics
TLDR
Increased CT attenuation correlated with ICC tumor vascularity and increased tumor enhancement in the arterial phase was associated with chronic hepatitis, lower malignancy, and better survival. Expand
Sarcomatous intrahepatic cholangiocarcinoma
TLDR
A new case of a patient with sarcomatous ICC who had no radiographic sign of intrahepatic tumor preoperatively is presented, suggesting that multidisciplinary approaches may be key to improve prognosis, including adjuvant chemotherapy or radiotherapy. Expand
Bile duct adenoma: imaging features and radiologic–pathologic correlation
TLDR
Bile duct adenoma can be characterized as a small semicircular lesion located in the liver subcapsular region, which show hypervascularity in the early phase with prolonged enhancement in the delayed phase. Expand
Intrahepatic Mass-Forming Cholangiocarcinoma: Relationship Between Computed Tomography Characteristics and Histological Subtypes
TLDR
Preoperative MDCT features of IMCCs can help differentiate the SD and LD types and predict patient prognosis and patients of MDCT-suggested SD type without lymph node enlargement demonstrated significantly better overall survival. Expand
Enhancement patterns of intrahepatic cholangiocarcinoma: comparison between contrast-enhanced ultrasound and contrast-enhanced CT.
TLDR
CEUS had the same accuracy as CECT in diagnosing ICCs, and so can be used as a new modality for the characterization of ICC. Expand
Enhancement characteristics of cholangiocarcinomas on mutiphasic helical CT: emphasis on morphologic subtypes.
TLDR
Cholangiocarcinoma subtypes tended to exhibit distinct enhancement characteristics that may aid diagnosis and surgical planning, according to retrospectively reviewed CT images. Expand

Intrahepatic Peripheral Cholangiocarcinoma: Two‐Phased Dynamic Incremental CT and Pathologic Correlation
TLDR
Two-phased dynamic incremental CT scans of 20 cholangiocarcinomas in 16 patients were carefully analyzed and found that most of the tumors appeared hypodense in the early phase and had increased CT numbers in their delayed images. Expand
Peripheral cholangiocarcinoma and clonorchiasis: CT findings.
TLDR
Peripheral cholangiocarcinoma should be the primary diagnostic consideration when these characteristic CT findings are detected in a noncirrhotic patient. Expand
Peripheral cholangiocarcinoma: comparison of MRI with CT
TLDR
MRI was slightly superior toCT in detecting the tumors, was inferior to CT in delineating focal ductal dilatation around the tumor, and was equal to CT on assessing extent of the tumors. Expand
Peripheral cholangiocarcinoma of the liver: two-phase spiral CT findings.
TLDR
Thin, mild, incomplete rimlike contrast enhancement at the tumor periphery and markedly low intratumoral attenuation with amorphous areas of slightly high attenuation during both scanning phases are typical findings of peripheral cholangiocarcinoma. Expand
MR imaging of intrahepatic cholangiocarcinoma
TLDR
The typical MR appearance of intrahepatic cholangiocarcinoma is a large well-delineated nonencapsulated tumor associated with intra hepatic venous encasement. Expand
Intrahepatic cholangiocarcinoma: radiologic-pathologic correlation.
TLDR
The following features may be helpful in differentiating ICAC from other primary intrahepatic tumors, particularly typical hepatocellular carcinoma: a homogeneously echogenic or high-attenuation appearance on images that reflects the uniform nature observed at pathologic examination, the presence of calcification, and the uncommon invasion of portal or hepatic veins. Expand
Cholangiocarcinoma: delayed CT contrast enhancement patterns.
TLDR
Delayed tumoral contrast enhancement is a typical feature of intrahepatic cholangiocarcinoma and may aid in the detection and characterization of such lesions at CT. Expand
Contrast-enhanced CT of intrahepatic and hilar cholangiocarcinoma: delay time for optimal imaging.
TLDR
Delayed CT images are helpful for tumor characterization and may improve observer confidence for the presence of tumor in patients who have intrahepatic or hilar cholangiocarcinoma. Expand
CT of hepatic tumors: prevalence and specificity of retraction of the adjacent liver capsule.
TLDR
Capsular retraction of the liver adjacent to hepatic tumors is an uncommon CT finding that appears to be specific for malignant hepatic tumor types. Expand
Imaging of intrahepatic cholangiocarcinoma: 1. Peripheral cholangiocarcinoma.
TLDR
The appearances of peripheral cholangiocarcinoma are reviewed and the various imaging techniques that can be used to evaluate this unusual tumor that is often resectable and potentially curable are discussed. Expand
