A case of hypervascular tumors in the liver and pancreas: synchronous hepatocellular carcinoma and pancreatic metastasis from renal cell carcinoma 36 years after nephrectomy.

It is sometimes difficult to distinguish between multiple cancers and metastases using only diagnostic imaging, particularly when multiple hypervascular tumors are found in multiple organs. We present a case in which the preoperative histological evaluation was essential to determine the management of a hypervascular pancreatic tumor and liver tumor.
