Ultrasonographic manifestations of hepatic hemangioma: I. The liver has limited enlargement, thickening and irregular contour. Second, the lesion area is large in scope and irregular in shape, and the boundary with the surrounding tissues may not be clear in some cases. Third, the internal echogenicity of the lesion varies in intensity, showing striated or honeycomb, and there are anechoic areas of different sizes and irregular morphology, such as the presence of calcified foci, there may be a small area of strong echogenicity, accompanied by acoustic shadows. Fourth, if the lesion is located under the rib margin or the subxiphoid process, slightly increase the pressure of the probe, the anterior and posterior diameters of the lesion area can often be observed to shrink, and the internal anechoic area is also reduced at the same time, and after removing the pressure, the image is still restored to the original image. The posterior echoes are not enhanced. Sixth, the lesion area can often show more stripes, point-like venous blood flow, some blood flow and the surrounding liver tissue blood flow, such as the detection of lesions within the sinusoidal venous blood flow, the diagnosis can be confirmed.
