A Wilms’ Tumor with Spinal Cord Compression: An Extrarenal Origin?

Figure 1

(a) Magnetic resonance imaging (MRI) showed an encapsulated tumor, with signs of capsular effraction at the upper pole of the left kidney. (b) Magnetic resonance imaging (MRI) showed a tumor, forming an intraspinal mass from T11 to L1 and compressing the spinal cord (arrow). (c) The left nephrectomy presented macroscopically a large tumor attached to the kidney without renal infiltration. (d) The microscopical examination confirmed the separation between the tumor and the kidney (Hematein-Eosin-Safran, ×100). (e) Wilm’s tumor, with regressive changes, of intermediate risk with only small areas of blastema (Hematein-Eosin-Safran, ×400).
