Interval development of heterogeneous retro-peritoneal mass lesion measuring about 5.6 x 4.1 cm encasing the inferior vena cava and surgical sutures of right nephrectomy. There is also interval development of a small nodule measuring 1.1 x 2.1 cm within the right renal fossa and a small enhancing lesion measuring 1.2 x 1.4 cm at the base of the urinary bladder in the region of right vesicoureteric junction. A few enlarged aortocaval lymph nodes seen adjacent to the aforementioned retroperitoneal mass.
Impression: Scan features are suggestive of recurrent disease in the renal fossa as well as at the right vesicoureteric junction. Stable suspicious irregular mass lesion in the gastric fundus adjacent to the gastroesophageal junction.
