. To demonstrate MRI characteristics of focal nodular hyperplasia and its classification ( classic and non classic types)
. To educate participants regarding variety of lesions which mimic focal nodular hyperplasia along with histopthological correlation and ensure treatment and management of such lesions
FNH is a hyperplastic process in which all normal constituents of liver are present but in an abnormally organized pattern The presentation includes review of MR examination for characterization of liver lesions such as FNH and its mimics using dedicated MRI abdomen protocol.with and without contrast medium ( Multihance) and hepatobiliary agents used for problem solving cases.
Focal nodular hyperplasia is second most common benign liver tumor after hemangioma and is incidentally discovered during cross sectional imaging.
FNH classification
Classic type 80%
Non-classic type 20%) includes
-Telangiectatic FNH
-FNH with cytologic atypia
-Mixed hyperplastic and adenomatous FNH
MIMICS
HCC
Fibrolamllar,
Cholangiocarcinoma
Hypervascular metastases
Hepatic adenoma
Hemangioma
Nodular regenerative hyperplasia
THID
Conclusion: MRI is invaluable tool in diagnosing primary liver lesions such as FHN and its mimics due to its excellent soft tissue contrast and helpful in management of such conditions
