Role of imaging in chronic otitis media and its complications

Figure 1 Otomastoiditis and accompanying cholesteatoma. A: The axial pre-contrast T1W; B: Post-contrast T1W; C: 3D-constructive interference in a steady state MR images show hyper-enhanced inflammatory alterations in the mastoid cells and middle ear on the right side (orange arrows); D: The axial diffusion-weighted; E: Apparent diffusion coefficient map; F: Coronal post-contrast T1W magnetic resonance images show the presence of cholesteatoma in the right inferior mastoid cells, which was not enhanced, but had significant diffusion restriction (blue arrows).
