  2. Focal nodular hyperplasia - Wikipedia

    en.wikipedia.org/wiki/Focal_nodular_hyperplasia

    Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases. Microscopically, a lobular proliferation of bland-appearing hepatocytes with a bile ductular proliferation and malformed vessels within the fibrous scar is the most common pattern.

  3. Liver tumor - Wikipedia

    en.wikipedia.org/wiki/Liver_tumor

    Focal nodular hyperplasia (FNH) is the second most common benign tumor of the liver. [2] FNH is found in 0.2%– 0.3% of adults worldwide. [2] FNH is more common in females (10:1 female to male ratio) except in Japan and China, in which there is a more equal prevalence of cases between females and males. [2]

  4. Liver biopsy - Wikipedia

    en.wikipedia.org/wiki/Liver_biopsy

    Multiphasic MRI is useful in diagnosing various types of liver lesions such as hepatocellular carcinoma, cholangiocarcinoma, hepatocellular adenoma, focal nodular hyperplasia, and hemangioma. [19] FibroTest (FibroSure in the USA) and FibroMax are non-invasive tests using a blood sample and an algorithm.

  5. Hepatocellular adenoma - Wikipedia

    en.wikipedia.org/wiki/Hepatocellular_adenoma

    Given that several liver tumors appear similarly on these imaging modalities, a multi-phase contrast-enhanced imaging study such as CT or MRI may be used to provide more information. [ 3 ] [ 4 ] The significance of making a specific diagnosis is that, unlike other benign liver tumors such as hemangioma and focal nodular hyperplasia, hepatic ...

  6. Nodular regenerative hyperplasia - Wikipedia

    en.wikipedia.org/wiki/Nodular_regenerative...

    Nodular regenerative hyperplasia (NRH) is a rare liver disease, characterised by the growth of nodules within the liver, resulting in liver hyperplasia.While in many cases it is asymptomatic and thus goes undetected – or is only discovered incidentally while investigating some other medical condition – in some people it results in non-cirrhotic portal hypertension (NCPH).

  7. Fibrolamellar hepatocellular carcinoma - Wikipedia

    en.wikipedia.org/wiki/Fibrolamellar_hepato...

    Diagnosis is normally made by imaging (ultrasound, CT or MRI) and biopsy. [17] However, even with a biopsy, there is often disagreement over the diagnosis. [ 17 ] Since the characterization of the DNAJB1::PRKACA fusion, the most reliable diagnosis is through molecular characterization such as PCR to detect the fusion, [ 7 ] [ 18 ] or genomic ...

  8. Cavernous hemangioma - Wikipedia

    en.wikipedia.org/wiki/Cavernous_hemangioma

    On CT or MRI scans, it shows peripheral globular/nodular enhancement in the arterial phase, with portions of attenuation of enhancing areas. In the portal venous phase, it shows progressive centripetal enhancement. In delayed phase, it shows retention of contrast. It shows a high signal on T2 weighted images. [24]

  9. Lymphoid hyperplasia - Wikipedia

    en.wikipedia.org/wiki/Lymphoid_hyperplasia

    Lymphoid hyperplasia is the rapid proliferation of normal lymphocytic cells that resemble lymph tissue which may occur with bacterial or viral infections. [1] The growth is termed hyperplasia which may result in enlargement of various tissue including an organ, or cause a cutaneous lesion .
