The study of postoperative ear cavities in patients who underwent surgery for cholesteatoma is a difficult challenge for radiologists. In our study we make a correlation between CT and MRI findings, useful tools in patients with suspected residual or recurrent cholesteatoma. The use of different MRI sequences especially DWI can help radiologists to discriminate between cholesteatoma and other different processes.
