This is a variant and is a bulge that is believed to form in development as the kidney interacts with pressure from the spleen.
Since you can't say for sure what this is on regular imaging, a CT scan or MRI is used to exclude other types of masses.
The position of the bulge is what is typical for the dromeduary hump, and obviously that position is correct on ultrasound. Ultrasound dose not show contours and densities precisely however...hence the CT....just a precaution.

Good Luck
