Patient
male, 61 year(s)
 
 
  • Figure 1
    Computed Tomography (CT) of the upper abdomen
     

    Unenhanced helical computed tomography (CT) shows a solitary, small hypodense rounded mass with well-defined margins within pancreatic tail. Hyperdense rim (arrow heads) is appreciated at the periphery of the mass.

     
    Area of Interest: unknown; Imaging Technique: Computed Tomography (CT) of the upper abdomen;

    Enhanced helical CT, acquired in arterial-phase shows marked contrast medium uptake. Splenic vein is of normal morphology and the fat plane between the vessel and the pancreas is prevented.

     
    Area of Interest: unknown; Imaging Technique: Computed Tomography (CT) of the upper abdomen;

    Enhanced helical CT, acquired in arterial-phase at a lower level than Fig 1b confirms left nephrectomy.

     
    Area of Interest: unknown; Imaging Technique: Computed Tomography (CT) of the upper abdomen;

    Enhanced helical CT, acquired in portal venous-phase shows early wash-out of the mass, which now appears hypodense.

     
    Area of Interest: unknown; Imaging Technique: Computed Tomography (CT) of the upper abdomen;
     
     
  • Figure 2
    Magnetic resonance (MR) of the upper abdomen
     

    Magnetic resonance (MR) of the pancreas, spin-echo T1-weighted image [TRms/TEms = 600/12] shows a hypointense mass characterized by peripheral markedly hypointense rim (arrow heads).

     
    Area of Interest: unknown; Imaging Technique: Magnetic resonance (MR) of the upper abdomen;

    MR of the pancreas, turbo spin-echo T2-weighted image [TRms/TEms = 5500/140] shows a relative hyperintensity of the mass compared with the surrounding pancreatic parenchyma. There is ectasia of the main pancreatic...

     
    Area of Interest: unknown; Imaging Technique: Magnetic resonance (MR) of the upper abdomen;

    MR of the pancreas, turbo spin-echo T2-weighted image contiguous to Fig 2b confirms the hypointense perilesional rim (arrow heads), compatible with a pseudocapsule.

     
    Area of Interest: unknown; Imaging Technique: Magnetic resonance (MR) of the upper abdomen;

Histologic examination of the surgical specimen. Hematoxylin-eosin stain; Topographic view x100: renal cell carcinoma metastasis (M) to the pancreas (P). Fibrosclerotic tissue (asterisks) is interposed between M and P. Insert x250: delicate fibrovascular cores are lined by cells with clear cytoplasm (pancreatic metastasis of renal cell carcinoma, clear cell type).
