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

Pure and mixed fibrolamellar hepatocellular carcinomas differ in natural history and prognosis after complete surgical resection. However, in cases of advanced cirrhosis, the contrast uptake by the liver parenchyma may be compromised by decreased hepatocytes function, which would result in reduction of the method’s accuracy to detect HCCs 4 Vilgrain V, Vullierme MP.

Female, year-old patients presenting with liver steatosis and multiple, well-defined focal hypervascular lesions, with intermediate signal intensity on T2- weighted riferencial, with poor lesion-organ contrast-enhancement. Open in a separate window. Advances in anatomic pathology ; 14 3: On the other hand, poorly-differentiated or undifferentiated hepatocarcinomas do not contain functioning hepatocytes and do not show hepatobiliary contrast uptake, remaining hypointense in relation to the surrounding parenchyma 21017 – 19 Figure 6.

Gastroenterology ; 2: As necessary, heavily T2-weighted cholangiographic images should also be acquired before the contrast injection, since hepatobiliary contrast agents are excreted by the biliary tract and can shorten the T2-relaxation time.

Male, year-old patient presenting with chronic C virus hepatopathy. A potential confusion factor is the fact that some hemangiomas may present subtle central contrast uptake during the early hepatobiliary phase because of the tendency to persistent centripetal enhancement at dynamic study, like in those with extracellular gadolinium 1.

Hepatobiliary-specific MR contrast agents: Consequently, the hepatobiliary phase acquisition time is different for each type of contrast agent and should be obtained minutes after gadobenate dimeglumine administration ranging between 1 and 3 hoursand 20 minutes after gadoxetic acid administration ranging between 10 and minutes 1.

Hepatobiliary contrast uptake by HCCs depends on the tumor differentiation stage and on the amount of functioning hepatocytes 24.

Fibrolamellar hepatocellular carcinoma: a case report

Received Jul 23; Accepted Oct Imaging of fibrolamellar hepatocellular carcinoma. Hepatocytes are responsible for the uptake and excretion of diaghostico hepatobiliary contrast medium, so their integrity is essential for the enhancement of the parenchyma in the hepatobiliary phase. Contrast uptake is also observed in focal liver lesions with functioning hepatocytes 1. Support Center Support Center. Journal of clinical oncology: Adverse effects of hepatobiliary contrast agents rarely occur and, if present, are similar to the ones reported in the use of extra-cellular gadolinium.

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.

Cancer ; Patients with cirrhosis Child Hepatocarcknoma or B do not present any significant alteration in the total clearance of hepatobiliary contrast agents; but in cirrhosis Child C, there is a decreased total clearance and increased half life, with compensatory increase of renal excretion 8.

Clinicopathologic characteristics and survival outcomes of patients with fibrolamellar carcinoma: Hemangiomas generally diagnostkco typical imaging findings and are easily diagnosed by computed tomography or MRI with extracellular gadolinium contrast agent.

Hepaatocarcinoma the postoperative follow-up, inadvertent ductal ligation can also be easily recognized in the hepatobiliary phase as an abrupt interruption of the biliary tract 45.

MR Imaging of hepatocellular carcinoma in the cirrhotic liver: Arterial embolization in the treatment of hemobilia after hepatic trauma: The use of hepatobiliary contrast agents may reduce the need for invasive diagnostic procedures and further investigations with other imaging hepatocacrinoma, besides the need for imaging follow-up.

Phase II trial of systemic continuous fluorouracil and subcutaneous recombinant interferon Alfa-2b for treatment of hepatocellular carcinoma.

The main indications for the method include: In cirrhosis, the hepatobiliary contrast uptake by the nodules depends on their differentiation stage and on diagnowtico presence of functioning hepatocytes. Radiology ; 1:
