Representative axial cut images of the abdominopelvic contrast-enhanced computed tomography (CECT) scan. (a): CECT performed in July 2020 showing a mild interval decrease in left kidney hypo-enhancing lesion from 41 x 38 mm to 33 x 29 mm (yellow arrow) and similarly a decrease in size of the retroperitoneal node from 20 x 16 mm to 19 x 10 mm. (b): CECT performed in December 2020 showing a decrease in size in the left kidney hypo-enhancing lesion from 33 x 29 mm to 28 x 26 mm (red arrow). (c): CECT performed in September 2021 showing significant reduction in size of renal mass from 41 x 38 mm to 28 x 24 mm (green arrow) and retroperitoneal nodes from 20 x 16 mm to 16 x 9 mm.
