Promising new non–echo-planar diffusion-weighted imaging techniques used in the diagnosis of cholesteatoma are presented, with emphasis on … The mass is lined by epithelium (facing inwards) which continues to grow, thereby shedding additional cells into the mass. Their cholesterol content (which is not always present) is responsible for their name, although 'keratoma' is probably a more apt term.
