The white spots look like either a disease or a scar. Hard to tell from those photos.

A scar should be smooth and clean on the surface... disease should be rough, scaley (like our own skin when we have an infection, etc.)

Also, if this is a disease process, it may change in shape or size over time.

Might want to have a vet look at it.

But I also have a question relating to the white spots... is this snake a mouse eater?

The position and size of the white spots is suggestive of a mouse bite from feeding live prey...
