Belo Horizonte, MG, Hepatobiliary-specific MR contrast agents: 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.

AMA journal of diseases of children ; 91 2: Recent results in cancer research Fortschritte der Krebsforschung. The hepatobiliary phase may also be useful in the post-chemoembolization or post-radiofrequency ablation follow-up, considering that inflammatory reactions show hepatobiliary contrast uptake and residual HCC tends to not present contrast uptake Modern imaging evaluation of the liver: 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.

Magnetic resonance imaging MRI with intravenous contrast injection extracellular gadolinium-based contras media commonly utilized in the radiological practice is considered the best imaging method in the evaluation of such lesions.

The use of hepatobiliary contrast agents requires some care. 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.

Additionally, hepatobiliary contrast agents allow for evaluating the biliary tract 1 – 3.

Case Report of Fibrolamellar Hepatocarcinoma, a Rare Tumor of Young Adults

Primary and secondary hepatic neoplasms. MR Imaging of hepatocellular carcinoma in the cirrhotic liver: The metastatic implants that do not contain hepatocytes become hypointense. 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. High-grade dysplastic nodules contain functioning hepatocytes and also demonstrate hepatobiliary contrast uptake in the same way as the surrounding parenchyma Figure 5.

Radiology ; 3: Gastrointestinal tumors of childhood. How to cite this article. Radiology ; 1: Pure and mixed fibrolamellar hepatocellular carcinomas differ in natural history and prognosis after complete surgical resection. Hemangiomas generally present typical imaging findings and are easily diagnosed by computed tomography or MRI with extracellular gadolinium contrast agent.

Services on Demand Journal. The differentiation between HCC and perfusion alterations may also represent a diagnostic challenge.

However, in some cases, especially those of small lesions without central scarone cannot differentiate between FNH and adenoma due to overlapping imaging findings 14. Imaging findings in the hepatobiliary findings should be always analyzed in the clinical context, considering the lesion signal characteristics on anatomical sequences.

Hepatobiliary contrast increases the method’s sensitivity to detect liver metastasis, particularly the small-sized ones. Received Jul 23; Accepted Oct Caroli’s disease complicated with liver abscess: Further potential hepatobiliary contrast applications include the evaluation of the functional hepatic reserve before partial hepatectomy; evaluation of live donor’s hepatic function as well as evaluation of early liver failure after transplant 4.

J Korean Soc Radiol. Metastases do not contain functioning hepatocytes or biliary ducts, and do not show contrast uptake during the hepatobiliary phase.

Current problems in diagnostic radiology ; 36 6: Also, hepatobiliary contrast-enhanced cholangiography allows for the accurate detection of postoperative complications such as biliary fistulas and bilomas which present progressive fill-in during the hepatobiliary phase.

Cancer ; 46 2: Benign liver lesions are frequently found, even in patients with known neoplasia. Vilgrain V, Vullierme MP. Although containing functioning hepatocytes, there is a lack of biliary ducts resulting in deficiency in bilirubin and hepatobiliary diagnostoco excretion. 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 characterization of focal liver lesions has a great clinical relevance. The most frequent differential diagnoses for hypervascular lesions in patients with no hepatopathy include hemangioma, FNH and adenoma. Considering that the presence of intralesional fat in NFH is rare, the patient will be maintained under imaging follow-up.

Fibrolamellar hepatocellular carcinoma: a case report

The presence of intralesional fat is not usually found in FNH and suggests the diagnosis of adenoma — adenomatosis, in the present case —, with a very different prognosis and approach.

Clinicopathologic characteristics and survival outcomes of patients with fibrolamellar carcinoma: Additionally, adenomas present smaller expression of difetencial transporters such as OATP1 12.

Hemangiomas normally have a typical presentation at MRI with extracellular contrast and are not an indication for investigation with hepatobiliary hepatocwrcinoma. The use of hepatobiliary contrast agents may reduce the need for invasive diagnostic procedures and further investigations with other imaging methods, besides the need for imaging follow-up.
