Degrees of hepatic steatosis are light, moderate and severe. Light hepatic steatosis is characterized by increased hepatic echogenicity with clear definition of the walls of the portal vein and the hepatic veins. Moderate hepatic steatosis is characterized by increased echogenicity with partial blurring of the walls of the portal vena and the hepatic veins. Severe hepatic steatosis has increased hepatic echogenicity combined with a loss of the posterior hepatic contours 102.
Los grados de esteatosis hepática se determinan como sigue: leve, presenta aumento de la ecogenicidad hepática, con clara definición de las paredes de la vena porta y venas hepáticas; moderada, con aumento de la ecogenicidad y borramiento parcial de las paredes de la porta y venas hepáticas; y severa, con mayor aumento de la ecogenicidad hepática y pérdida de los contornos posteriores hepáticos 102.
