Dromedary hump
From the case:
Dromedary hump
Ultrasound
Focal bulge in the mid-pole of the kidney. It can be mistaken for a renal mass, but on closer inspection it mimics the renal cortex in every respect.
Case Discussion
Dromedary hump is named after the camel of the same name. The focal bulge in the renal cortex, albeit striking in appearance, is just a focal bulge of normal cortex. It is a variant not uncommonly identified.
