Abdominal Computed Tomography. A: Before treatment, the scan shows three hypodense lesions in liver segments VIII, IV and VII, with a slightly hyperdense peripheral halo during the arterial phase of examination. B: after treatment, the lesions have no contrast enhancement and are smaller in size.

An abdominal CT scan revealed three lesions in liver segments VIII, IV and VII, suggestive for abscesses or metastasis (Fig. 1A). Two months after the beginning of treatment, radiological examination revealed a further reduction of the residual tumor tissue, indicating good response to treatment and the need to maintain an immunosuppressive action through a low dose of prednisone (12,5mg) (Fig. 1B).
Contrast-enhanced ultrasound examination (CEUS) 

A

: Before treatment, the image shows that the lesions are hypoechoic in the late phase of the examination. B: after treatment: the lesions have smaller size and appear lightly hypoechoic during the late phase of examination.

First, a CEUS was performed: the largest lesion appeared isoechoic in arterial phase and hypoechoic in portal and late phase (features suggestive for secondary hepatic nodules) (Fig. 2A). A CEUS examination showed any modification of distribution of contrast in the arterial phase and light hypoechogenicity of lesions in both portal and parenchimal phases (Fig. 2B).
