fibrolamelläres Leberkarzinom mit Verkalkungen

A case report

of fibrolamellar hepatocellular carcinoma, with particular reference to preoperative diagnosis, value of molecular genetic diagnosis, and cell origin. Dynamic computed tomography (CT) and gadoxetic acid-enhanced magnetic resonance imaging. A lobulated mass is visualized located in the anterior sector of the liver. The tumor was seen as a low-attenuating lesion in unenhanced images (A) and as a heterogeneous hyperattenuation in the arterial phase of dynamic CT (B). Hyperattenuation in the arterial phase suggests hypervascularity. The tumor demonstrated washout in the delayed phase of dynamic CT (C). The central scar showed a gradually enhancing pattern with calcification. The scar was seen as a hypointensity on T2WIs (D) and as a marked hyperintensity on DWIs (E). The tumor was visualized as a low signal intensity in the hepatobiliary phase, without gadoxetic acid uptake. Also, the tumor was observed as having a lobulated appearance in the hepatobiliary phase (F)
