Normal variant : Persistent fetal lobulation is a normal variant seen occasionally in adult kidneys. It occurs when there is incomplete fusion of the developing renal lobules.Embryologically, the kidneys originate as distinct lobules that fuse as they develop and grow.It is often seen on ultrasound or ct as smooth indentations of the renal outline in between renal pyramids. They should be distinguished from scar.
