The superior vena cava and left innominate vein are completely obliterated due to chronic thrombosis. Numerous venous collaterals are seen at the chest wall and mediastinum. Intensely enhancing area within segment IV. Dilated paraumbilical veins are also noted.
Bilateral mild pleural effusion.
Case Discussion
Following superior vena cava obstruction, a pseudolesion, called the hepatic hot spot sign, may occur secondary to portosystemic venous shunting between the superior vena cava and the left portal vein through the internal mammary and paraumbilical veins along the ligamentum teres.
