An abdominal ultrasound examination showed multiple hepatic heterogeneous mass lesions, with the largest one in size of 40.6*32.1 mm (arrow).

Abdominal ultrasound revealed more than 8 heterogeneous, hyperechoic, and hypervascular nodular to mass-like hepatic lesions with the largest one over left lobe (Fig. 1).
The precontrast CT scan illustrates nodules and masses of low attenuation in the liver, with the largest one in size of 25*40 mm at the left lobe. CT = computed tomographic.

The largest one was 25*40 mm at left lobe of the liver (Fig. 2).
The arterial phase CT scan reveals enhancement of the lesions within the liver. CT = computed tomographic.

After intravenous injection of contrast medium (arterial phase) (Fig. 3), the lesions were dominantly enhanced.
In portal venous phase of CT scan, all lesions showed progressively increased areas of contrast enhancement with centripetal pattern. CT = computed tomographic.

All lesions showed progressively increased areas of contrast enhancement with a centripetal pattern in portal venous phase (Fig. 4).
In delayed phase of CT scan, majority of the lesions became homogeneous enhancement while the largest lesion manifested incomplete enhancement, probably related to necrosis or fibrosis (arrows). CT = computed tomographic.

In delayed phase (Fig. 5), the majority of the lesions became homogeneous enhancement while the largest lesion demonstrated incomplete enhancement, probably related to necrosis or fibrosis.
No lesions were detected under abdominal ultrasound after a 4.5-month treatment course of propranolol.

After a total of 4.5-month treatment, no more hepatic lesions could be detected by abdominal ultrasound (Fig. 6).
