Not hepatic infarction: Cold quadrate sign

A 50-year-old male presented with bilateral lower extremity plain is found to have a wedge-shape hypodense region in the hepatic quadrate lobe. The hypoenhancement was thought to be a result of systemic-portal venous shunting due to IVC obstruction, a “cold” version of the classically described hot quadrate sign. Follow-up CT confirmed the diagnosis. Venous drainage pathway for both hot and cold quadrate signs is discussed.
