Fibrolamellar hepatocellular carcinoma: a case report
Belo Horizonte, MG, Hepatology ; 55 3: The lesions in segments VII and VIII arrows are similar, with marked hypersignal on T2-weighted, hyposignal on T1-weighted sequence, and nodular, peripheral and discontinuous uptake in the arterial phase, a characteristic of hemangiomas. Female, year-old patient with liver nodules to be clarified. The usual dynamic study with arterial, portal and delayed phases is also performed with such contrast agents.
Primary liver carcinoma arising in people younger than 30 years. The different enhancement patterns depend on the histological grade of the HCCs and may be explained by the membrane transporters expression.
Case reports in oncology ; 5 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 duagnostico. Magnetic resonance imaging is considered the best imaging method for evaluating such lesions, but does not allow for the diagnosis in all cases.
J Korean Soc Radiol. Patients with advanced liver and kidney diseases alternatively compensate the contrast agents clearance by renal or biliary excretion, respectively. Such lesions present functioning hepatocytes, suggesting FNHs as the main diagnostic hypothesis and ruling out the possibility of diagnostixo implants.
Case Report of Fibrolamellar Hepatocarcinoma, a Rare Tumor of Young Adults
Perfusional alterations present a signal similar to the one of the remainder hepatic tissue during the portal and hepatobiliary phases, while most HCCs, except the well-differentiated ones, present hyposignal in the hepatobiliary phase Main indications for hepatobiliary contrast include differentiation between focal nodular hyperplasia FNH and adenoma, characterization of hepatocelular carcinomas HCCsdetection of small liver metastasis, assessment of biliary anatomy, and characterization of postoperative biliary fistulas.
Computed tomography of body with magnetic resonance imaging. Support Center Support Center. The conclusions eiagnostico the importance of radiological imaging for the detection and characterization of hepatic focal neoplasms.

In cirrhosis, the hepatobiliary contrast uptake by the nodules depends on their differentiation stage and on the presence of functioning hepatocytes.
The imaging evaluation of the biliary system has been approached by a series of publications in the Brazilian radiological literature 24 – The main indications for the method include: Fibrolamellar variant of hepatocellular carcinoma does not have a better survival than conventional hepatocellular carcinoma–results and treatment recommendations from the Childhood Liver Tumour Strategy Group SIOPEL experience.
Is fibrolamellar carcinoma different from hepatocellular carcinoma? The largest ones tend to present signal heterogeneity, with mild to moderate hypersignal on T2-weighted, hyposignal on T1-weighted sequences, homogeneous or heterogeneous arterial contrast-enhancement, late washout, and possible development of capsule Radiology ; 3: Contrast enhancement of liver lesions in cirrhotic patients: The presence of intralesional fat is not usually found in FNH and suggests the diagnosis of adenoma — adenomatosis, in the present case —, with a viagnostico different prognosis and approach.
Fibrolamellar hepatocellular diefrencial in children and adolescents. 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. Advances in anatomic pathology ; 14 3: As gadoxetic acid is utilized, the hepatobiliary phase occurs in 20 minutes, so it is recommended that the order of sequences acquisition be changed in order to optimize the acquisition time.
The use of hepatobiliary contrast agents requires some care.
This article has been cited by other articles in PMC. On the other hand, difedencial lesions showed homogeneous hepatobiliary contrast uptake, hence the highest likelihood of the diagnosis of multiple FNHs.
Small nodules are observed adjacent to the gallbladder, with hyposignal on T2-weighted sequence, without expression on the other sequences and on the conventional dynamic study, but with hepatobiliary contrast uptake, leading to the diagnosis of regenerative nodules. Imaging findings in the hepatobiliary findings should be always analyzed in the clinical context, considering the lesion signal characteristics on anatomical sequences.
The most frequent differential diagnoses for hypervascular lesions in hepatocarcinomaa with no hepatopathy include hemangioma, FNH and adenoma. The utilization of hepatobiliary contrast agents increases the MRI accuracy, reducing the necessity of invasive diagnostic procedures intended to clarify the diagnosis of nonspecific lesions 12. Cancer ; 97 8:
