Such lesions present functioning hepatocytes, suggesting FNHs as the main diagnostic hypothesis and ruling out the possibility of metastatic implants.

Find articles by Daniella Braz Parente. Cancer ; 46 2: Low-grade regenerative and dysplastic nodules present preferentially portal vascularization, contain functioning hepatocytes and, like the surrounding parenchyma, show hepatobiliary contrast uptake.

The presence of central scar markedly hyperintense on T2-weighted and hypointense on T1-weighted sequences, with no contrast uptake in the arterial phase and late contrast uptake is typical. Hepatology ; 39 3: Adenomas are well defined, homogeneous or heterogeneous hepatocarcioma.

Journal of hepatology ; 56 4: FNH is a benign lesion that does not require any intervention, while adenoma presents risk for malignization, necrosis and bleeding which might require emergency surgery. Distinguishing hypervascular pseudolesions of the liver from hypervascular hepatocellular carcinomas with gadoxetic acid-enhanced MR imaging.


Focal hepatic lesions, Hepatobiliary contrast, Magnetic resonance imaging. FNH presents greater density of functioning hepatocytes than a healthy liver parenchyma, in association with abnormal bile ducts which do not communicate with greater bile ducts, with consequential slower biliary excretion as compared with the surrounding liver. Journal of the American College of Surgeons ; 6: No hepatobiliary contrast uptake is observed.

Fibrolamellar hepatocellular carcinoma: a case report

Thus, high-grade dysplastic nodules tend to be hypovascular in the arterial and portal phases, but may also become hypervascular in the arterial phase in cases where the abnormal arterial vascularization is more developed. The differentiation between HCC and perfusion alterations may also represent a diagnostic challenge.

Review of the clinicopathologic features of fibrolamellar carcinoma.

The largest lesion arrows presents high signal intensity on T2-weighted, hyposignal on t1-weighted sequence, and nodular, peripheral and discontinuous uptake in the arterial-phase, and no hepatobiliary contrast uptake that is a typical hemangioma behavior. Spontaneous perforation of gallbladder with intrahepatic biloma formation: In the hepatobiliary phase, the healthy liver is evenly enhanced, becoming hyperintense; the contrast agent uptake by the biliary tract occurs progressively, and the blood vessels become hyperintense as compared with the liver parenchyma as the contrast medium is no longer in the vascular compartment.

The conclusions reinforce the importance of radiological imaging for the detection and characterization of hepatic focal neoplasms. Like in cirrhosis, perfusional alterations in patients with metastasis show contrast uptake in the hepatobiliary phase, differently from metastases 1.

Case reports in oncology ; 5 1: Also, in the delayed-phase, the fill-in pattern is not observed, which might occur with the diagonstico of hepatobiliary contrast agent.


Contrast enhancement of liver lesions in cirrhotic patients: However, considering that hemangiomas are common lesions, they will be frequently present on images acquired with hepatobiliary contrast for several reasons.

The largest ones tend to present signal heterogeneity, with mild to moderate hypersignal on T2-weighted, hyposignal on T1-weighted sequences, hepatodarcinoma or heterogeneous arterial contrast-enhancement, late washout, and possible development of capsule Modern imaging evaluation of the liver: The different enhancement patterns depend on the histological grade of the HCCs and may be explained by the membrane transporters expression.

Two hypervascular lesions arrows are seen with intermediate signal intensity on T1- and T2- weighted sequences, showing contrast uptake in the hepatobiliary-phase.

A fraction of hepatobiliary contrast agent is excreted by cMOAT into the biliary canaliculi multispecific canalicular organic hepatocarcinnoma transporter 1.

The caudate lobe lesion arrowheads presents subtle hypersignal on T2-weighted sequence and signal loss on T1-weighted out-of-phase sequence caused by the presence of intralesional fat.

Pure and mixed fibrolamellar hepatocellular carcinomas differ in natural history and prognosis after complete surgical resection.
