A well defined rounded lesion is seen at the left lower renal hilum related to renal vessels, elicits mixed low and high densities in non-enhanced CT with marginal punctuate mural calcifications, It shows partial eccentric intense enhancement in the arterial and portal phases similar to the blood pool, the remaining part appears hypodense and not enhanced with surface irregularities.
The posterior aspect of the left kidney shows hypodensity in the arterial phase with diminished cortical enhancement.
Few smaller renal stones are incidentally seen bilaterally.
