US Sagittal ? Dromedary Sign
A dromedary sign or hump is a focal bulge on the lateral aspect of the left kidney. It is a normal variant. It is called the “dromedary sign” because the bulge resembles the hump on a dromedary camel. It is felt to be related to the mass effect on the spleen on the left kidney
