Patient Data
A 58×50mm partially exophytic mass is seen in the right kidney. The neoplasm has a similar density to normal renal parenchyma on non-enhanced CT scan. After IV contrast media injection, the attenuation value increased from 23HU to 110HU. Nephrographic-phase CT scan shows that the mass enhances less than normal renal parenchyma.
Mild perinephric fat stranding is present. There is no sign of local invasion to adjacent structures, No vascular extension and no regional lymphadenopathy.
The gallbladder is not seen at anatomical location due to prior resection.
Degenerative changes as osteophytosis are seen at the lumbar spine.
