Hepatocellular carcinoma presenting as an extrahepatic mass: A case report and review of literature

Figure 1 Lesion growth on computed tomography. Serial intravenous-contrasted Computed tomography scans of the abdomen and pelvis demonstrated increase in size of the patient’s portocaval mass (arrows). A: 3.6 cm × 2 cm, 8 months prior to presentation; B: 5.2 cm × 3.2 cm, time of presentation.

Figure 2 Histopathologic evaluation of the resected mass. A: Hematoxylin and eosin staining at low and high magnification reveals vague nodules of large polygonal cells with eosinophilic granular to clear vacuolated cytoplasm, steatotic and clear-cell changes, increased mitosis, necrosis and rare hyaline bodies; B: Immunohistochemistry demonstrates positive staining for HepPar1, arginase-1, and glypican-3.

Figure 3 Magnetic resonance imaging of the liver. Magnetic resonance imaging abdomen demonstrated a 1.2 cm lesion in segment VIII with late arterial enhancement, fatty sparing, and intrinsic T1 hyperintensity. A: T1-weighted, pre-contrast; B: T1-weighted immediate post-contrast; C: T1-weighted, 5 min post-contrast.
