Note that the hypertrophied column is seen to enhance just like normal parenchyma in all phases, there is no mass effect.
This is a common cause of renal "pseudomass". on ultrasound the column spits the sinus echoes.
CECT is often done to resolve the issue. A hypertrophied column shows enhancement that is the same as normal cortex. It merges with the cortex and causes no contour deformity. These findings help to differentiate it from other pseudomasses such as fetal lobulation and a dromedary hump.
