Hepatic hemangioma lacks specific clinical manifestations, so its diagnosis mainly relies on the following items: 1. Ultrasound examination: Ultrasound manifestation of hepatic hemangioma is hyperechoic, hypoechoic and mostly accompanied by reticular structure, with uniform density, regular morphology and clear boundaries. At present, ultrasound is the main means of first diagnosis and primary screening. 2. Ultrasound examination: Typical hemangiomas show nodular or circumferential enhancement in the periphery during the arterial phase, and gradually expand to the center over time. The process of expansion is very slow, and the foci remain in the enhanced state in the portal or delayed phase, with echogenicity equal to or higher than the surrounding normal liver tissue; 3.Enhanced CT: CT scan shows well-defined round or circular-like low-density foci in the liver parenchyma, and a few may show irregular shape; 4.Magnetic resonance imaging: MRI shows low signal in T1-weighted term, and high signal in T2-weighted term. This is the specific performance of hemangioma in MRI, which is described as “light bulb sign”. At present, CT and MRI are the main tests for the diagnosis of hepatic hemangioma in China.
