Figure 1. Enhanced computed tomography scan (CT) demonstrated a 4.5×4.0×4.5cm neoplasm in the middle and dorsal part of left kidney (CT unit: 45). It had a clear boundary and part of the neoplasm extruded the renal contour. Multiple patchy low density area could be seen in the neoplasm (CT unit: 10). The neoplasm was lightly enhanced in the arterial phase (CT unit: 57.2), and it was continuously enhanced in the venous (CT unit: 68.9) and excretory phase (CT unit: 88.8). The low density area did not show any enhancement.

Figure 2. Gross pathologic features of the resected specimen. The cut section indicated a red-white cystic solid tumor mass measuring 5×4cm (A). The lesion was completely resected and accompanied with some fat covering the outer surface (B).
Figure 3
Figure 3. Postoperative pathological examination verified metanephric adenofibroma (×100). (A) Spindle cells proliferate and the cell size is consistent with a few acini and tubular structures scattering among them and some are cystic expansion. The lined epithelial cells did not show atypia. Immunohistochemical results show that vimentin is positive for tumor (B) and CK is positive for small tube and negative for tumor (C, D).
