A,B: Axial and coronal fast imaging employing steady-state
acquisition MRI with fat suppression. Solid, encapsulated, heterogeneous
expansive mass in the epigastrium (arrowhead), with lobulated contours and
areas of hyperintensity (arrow) consistent with necrosis. C:
T1-weighted MRI acquisition with fat suppression after intravenous
administration of paramagnetic contrast. Diffuse, heterogeneous paramagnetic
contrast uptake by the neoplasm. Note the areas without uptake, which is
consistent with necrosis (arrow). D: Macroscopic examination.
Specimen received in formalin, designated as the product of a left
hepatectomy, consisting of a liver fragment weighing 2354 g and measuring 23
× 17 × 11 cm, with an irregular shape, a smooth, brownish
external surface, and a bloody area that measured 10 × 6 cm.
