Imaging features of ultrasound and contrast-enhanced ultrasound in primary hepatic carcinosarcoma: three cases report.

Primary hepatic carcinosarcoma (PHCS) is a very rare malignant tumor with a poor prognosis. Previous studies in the English-language literature were case reports, focused on the clinical aspects, pathology and pathogenesis. Much is unknownabout the imaging characteristics of PHCS while ultrasound is the first imaging examination for hepatic disease. Contrastenhancedultrasound (CEUS) is a proven method that improves the detection and characterization of focal liver lesions. The purpose of the paper is to present the ultrasonographic and other imaging appearance of three cases of PHCS.
