Abstract

Typical ultrasonographic findings of hepatic hemangioma are well demarcated, hyperechoic, homogenous mass. In case of hepatic hemangioma accompanied by arterioportal shunt, hypoechoic halo can be identified due to dilution of portal blood by nonlipid-rich arterial blood. Hypoechoic halo can also be observed in patients with malignancy such as hepatocellular carcinoma, mass forming cholangiocarcinoma and metastatic cancer. Color doppler ultrasonography can depict penetrating artery, intratumoral flow and retrograde hepatofugal portal venous flow in patient with hepatic hemangiomas accompanied by arterioportal shunt. So in patients with hepatic hemangioma with hypoechoic halo, we have to differentiate from other diseases through clinical findings, color doppler ultrasonography, contrast-enhanced ultrasonography and computed tomography. Author reports a case of hepatic hemangioma with hypoechoic halo accompanied by arterioportal shunt with the help of color doppler, contrast-enhanced ultrasonography and computed tomography.
