“…Sclerosing hepatocellular carcinoma (HCC), also called scirrhous-type HCC, because of dense fibrous stroma histologically, could mimic LFTL even if it is more often seen following radiation exposure, chemotherapy, or infarction [8]. Metastasis, fibrolamellar HCC, and intrahepatic cholangiocarcinoma [9] are usually neither pedunculated nor encapsulated. Diagnosis of LFTL should be suspected when these imaging findings are observed.…”

“…The signal intensity of the tumor is variable according to the amount of fibrosis, necrosis, and mucinous material within the tumor. Central hypointensity may be seen on T2-weighted images, corresponding to central areas of fibrosis [62,63,64]. On dynamic contrast-enhanced MR studies, minimal to moderate peripheral enhancement is evident followed by progressive filling.…”

Focal liver lesions: MR imaging–pathologic correlation

et al. 2001

Magnetic resonance signal intensity of focal liver lesions is affected by numerous pathologic factors. Lesion histologic features, such as cellularity, vascularity, stromal component, and intratumoral necrosis or hemorrhage, strongly affect T1 and T2 relaxation times. Additionally, intracellular content of certain substances, such as glycogen, fat, melanin, iron, and copper, may also have a substantial role in determining MR signal behavior. In this review we discuss the correlations between MR imaging features and pathologic findings in benign and malignant focal liver lesions. Knowledge of imaging-pathology correlations greatly assist in charac terizing focal lesions. Moreover, in certain tumor histotypes, such as hepatocellular carcinoma, careful analysis of lesion signal intensity may help predict the degree of tumor differentiation.

“…In other CT and MR reports, CCAs have been described to have either heterogeneous or homogeneous delayed retention of contrast [5][6][7][8][9][10][11]. Differences between fibrous tumors showing delayed homogeneous versus heterogeneous retention of contrast remain uncertain.…”
