The signal intensity should be higher than visible on the dwi images with b value 0 s mm 2. It is the only entity that demonstrates high signal intensity on dwi. This case is a histologically proven case of cholesteatoma. However the sequence is prone to artefact and care must be taken how the sequence is performed and interpreted 2.

Cholesteatoma is not a neoplasm and can be thought of most simply as skin in the wrong place. For comparison the annual incidence of middle ear cholesteatoma is around 9 2 per 100 000. The overall incidence rate in one large study was 0 30 per year per 100 000 inhabitants 1. Although a cholesteatoma is histologically identical to an epidermoid or epidermal.

On the adc map a low signal should be visible in the same area confirming the presence of diffusion restriction. Findings are characteristic of an acquired cholesteatoma. On the dwi images with b value 1000 s mm 2 a cholesteatoma becomes apparent as a hyperintense area. Diffusion weighted imaging is particularly useful when distinguishing a cholesteatoma from other middle ear masses.
