Molecular pathogenesis of focal nodular hyperplasia and hepatocellular adenoma.
Focal nodular hyperplasia (FNH) and hepatocellular adenomas (HCAs) are benign tumors that occur in otherwise normal liver parenchyma. FNH is considered to be the result of a hyperplastic response to increased blood flow secondary to vascular malformations. Most FNH are polyclonal and to date, the molecular pathway and mechanisms that are altered in FNH have yet to be elucidated. In contrast, HC...
متن کاملImaging modalities for focal nodular hyperplasia and hepatocellular adenoma.
BACKGROUND/AIMS There are several imaging modalities available for the detection of focal liver lesions. Differentiation between focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA) is important because of the consequences for management. However, differentiation based on imaging alone still shows limitations. METHODS We reviewed the literature for typical features of FNH and HCA ...

متن کاملBenign Hepatocellular Tumors in Children: Focal Nodular Hyperplasia and Hepatocellular Adenoma
Benign liver tumors are very rare in children. Most focal nodular hyperplasia (FNH) remain sporadic, but predisposing factors exist, as follows: long-term cancer survivor (with an increasing incidence), portal deprivation in congenital or surgical portosystemic shunt. The aspect is atypical on imaging in two-thirds of cases. Biopsy of the tumor and the nontumoral liver is then required. Surgica...
متن کاملCT-Value (△HU and CT-Value ratioin) differential diagnosis of small hepatocellular carcinoma from focal nodular hyperplasia
Background: The objective was to explore the value of the CT value difference (△HU) and CT value ratio (CVR) between the hepatic arterial (AP), portal (PP), and delayed phases (DP) to differentiate the small Hepatocellular Carcinoma (SHCC, ≤ 3 cm) from the small Focal nodular hyperplasia (SFNH, ≤ 3 cm). Materials and Methods: All the lesions were confirmed by clinically and/or pathologically an...
