Contrast-enhanced ultrasound (CEUS) appearance of hepatic myelolipoma.

ABSTRACT

The case report is a description of a single case of hepatic myelolipoma, a very rare benign hepatic tumor, evaluated with contrast sonography, in a 72-year-old female. It was previously reported as hyperechoic lesions at sonography. CEUS features of the lesion were homogeneous hyperenhancement in the arterial phase and a slight hyperenhancement in the portal venous phase typical of benign tumors. The case report shows CEUS may help in differential diagnosis between benign and malignant lesions, but only the biopsy of the tumor and the pathological evaluation allows the diagnosis.
