Visualization of the internal mammary artery via the hepatic falciform artery in a patient with hepatocellular carcinoma

The hepatic falciform artery is a small vessel that arises as a terminal branch of the middle or left hepatic artery. Its anatomy and clinical importance have been described in several recent reports. During dissection of a cadaver, this artery is generally found connected with the ensiform branch of the internal mammary artery. However, to our knowledge, anastomosis has not previously been described radiologically.
