Preschooler with right hydronephrosis

Surgery image of retrocaval ureter causing ureteropelvic junction obstruction
Surgical image (above) shows the decompressed distal right ureter (with the black loop around it) emerging from behind the inferior vena cava in the center of the image. The dilated proximal right ureter can be see just to the right of the inferior vena cava at the top of the image. Post operative surgical image (below) shows the red vessel loops around the now decompressed proximal right ureter which has been transected and reanastomosed anterior to the inferior vena cava in the center of the image.

The diagnosis was retrocaval ureter causing ureteropelvic junction obstruction.

Preschooler with increased perspiration

Surgery image of pheochromocytoma
Surgical image shows a 6 cm dumbbell shaped tumor that was adherent to the inferior vena cava with tumor extension via the adrenal vein into the inferior vena cava. The dark ovoid mass in the center of the image is the main portion of the tumor. The glistening white smaller mass is a portion of the tumor inside the lumen of the opened inferior vena cava. Vascular clamps are on the inferior vena cava above and below the tumor.

The diagnosis was pheochromocytoma.
