Explanation:

Hepatic angiosarcoma is known to be etiologically linked to exposure to polyvinyl chloride (PVC) and Thorotrast (a radioactive contrast agent). Hepatocellular carcinoma has other common etiologies like viral hepatitis, cirrhosis; cholangiocarcinoma is linked to conditions like primary sclerosing cholangitis, parasitic infections; hepatic adenoma is associated with oral contraceptives, glycogen storage diseases. So the disease linked to PVC and Thorotrast is hepatic angiosarcoma.
