Steatotic, or Fatty, Liver

Description

Rendered as an enlarged adult liver with a smooth, glistening capsule, the organ’s right lobe dominates laterally while the smaller left lobe extends medially across the anterior surface. Subtle impressions along the inferior margin suggest the usual visceral relationships, even though the gallbladder fossa and porta hepatis are not opened in this external view. Steatosis is conveyed by overall swelling of the hepatic parenchyma rather than focal nodularity, consistent with fatty change at the level of the hepatic lobule. Fatty liver disease is often taught as a microscopic diagnosis, but gross morphology matters when you correlate hepatomegaly on physical exam with ultrasound or CT findings, where diffuse low attenuation and a rounded inferior margin can be the first clue to hepatic steatosis. Progressive nonalcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) can advance from reversible intracellular triglyceride accumulation to inflammation and fibrosis, so distinguishing a smooth, enlarged liver from a nodular cirrhotic surface has real implications for staging and management. Consider it alongside common mimics in practice. Alcohol-associated liver disease, drug-induced steatosis, and metabolic syndrome all land in the same differential. Use this 3D liver rendering in hepatobiliary anatomy teaching, pathology lectures on steatosis versus cirrhosis, or as a clean figure in review articles discussing NAFLD prevalence, imaging appearance, and biopsy indications, with the white background making it easy to label lobes and margins for slides.
