Figure 1
37-year old woman with von Hipple Lindau
disease. Radical right nefrectomy and partial tumorectomy in left kidney. (a) Axial contrast-enhanced CT scan shows scar
in the lower pole in the left kidney (arrow),
without any mass. Note the absence of right kidney. (b) One year later sagittal US scan
with a large mass less echogenic than renal sinus fat, involving the lower pole
parenchyma (arrows). (c) Axial contrast-enhanced CT
(nephrographic phase) scan obtained at the same time shows the mass that has
grown with perinephric extension (white arrow). It was a renal adenocarcinoma.
Note of the presence of paraaorthic lymph node (black arrow).
