case_images: Abdominopelvic spiral CT scan demonstrated a 38 mm x 30 mm x 43 mm hypodense solid mass in the midpole of the left kidney that enhanced after administration of contrast material (Figure 1).
case_images: Sections from renal mass show hyper cellular tumor with trabecular and
  nesting pattern. Individual tumor cells show salt and pepper nuclei
  (H&EX 250).
