Fig. 2From: Tumor-to-tumor metastasis: an extremely rare combination with renal cell carcinoma as the donor and a pancreatic neuroendocrine tumor as the recipientGd-DTPA-enhanced MRI findings of the pancreatic head tumor. The pancreatic tumor presented with homogenous hypointensity on a T1-weighted imaging and b T2-weighted imaging. c The pancreatic tumor presented with mild hyperintensity on diffusion-weighted imaging. d The aforementioned hypointensity was unclear on apparent diffusion coefficient mappingBack to article page
