The deer horn sign is a reliable sign and an important diagnostic clue of passive congestive hepatopathy due to heart failure on ultrasonography ¹. In the deer horn sign, the head is formed by a dilated inferior cava, and the engorged hepatic veins resemble horns. It has also been described as the bunny sign, which was first described by Bartrum and Crow ^2,3.
