K. Yoshimitsu et al., Fat detection in granular-cell renal cell carcinoma using chemical-shift gradient-echo MR imaging: another renal tumor that contains fat, ABDOM IMAG, 25(1), 2000, pp. 100-102
Preoperative chemical-shift magnetic resonance images in a 56-year-old man
suggested the presence of microscopic fat in the tumor, The surgical specim
en showed a granular-cell renal cell carcinoma with papillary architecture,
associated with abundant fat-containing foamy histiocytes in the interstit
ium. The radiologist should include this entity in the differential diagnos
es of renal tumors that contain microscopic fat.
