Film treatments are also referred to as story treatments, script treatments, and movie treatments.

Video games - A game treatment is a written summary of a game concept that included concept sketches of the game world and characters. In the gaming industry, game treatments are used to get feedback on game concepts, as well as pitch game concepts to get approval and funding to create them.
