Male 69 years old Reason: has kidney and prostate cancer; evaluate 2.5 cm caudate lobe mass History: none ABDOMEN:LIVER, BILIARY TRACT: There is a 2.2 x 2.1-cm T2 hyperintense lesion within the caudate lobe. This demonstrates incomplete peripheral nodular enhancement with progressive fill-in and is most consistent with a hemangioma.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Large heterogeneously enhancing left lower pole renal mass with central non-enhancement suggestive of necrosis. This measures at least 8.9 x 12.7 cm (series 801, image 87). Tumor extends into the left renal vein. No tumor is identified within the IVC. The right kidney is unremarkable.RETROPERITONEUM, LYMPH NODES: Multiple enlarged retroperitoneal lymph nodes.

1.Caudate lobe lesion is most consistent with hemangioma.2.Large left renal necrotic mass consistent with renal cell carcinoma. There is left renal vein invasion and metastatic retroperitoneal lymphadenopathy.3.L1 vertebral body metastasis.
