title: A case of primary liver carcinosarcoma: CT findings.
abstract: Primary liver carcinosarcoma is extremely rare. We report a case of liver carcinosarcoma in a 58-year-old man, which was identified by pathologic and immunohistochemical (IHC) examinations. Plain CT scans showed a hypodense mass in the right liver lobe adjacent to the gallbladder fossa. The triple-phase contrast CT scans showed a mixed density mass with inhomogeneous enhancement. Multiple cystic nodules with irregular rim enhancement of the margin located in the tumor. The gallbladder wall and transverse colon were involved. CT presentations of liver carcinosarcoma were unspecific and the pre-operative diagnosis is difficult.
