Abstract
- We report the CT findings of four cases of squamous cell carcinoma, paying special attention to the epicenter of the lesion and the pattern of bony destruction. All four patients had a past history of chronic otitis media. Squamous cell carcinoma affected mainly the hypotympanum and inferior wall of the external auditary canal, and in all cases revealed an irregular pattern of bony destruction. Irregular destruction of the tegmen tympani occurred in two cases. In cases of squamous cell carcinoma, CT findings suggesting involvement of the promontary are usually noted.
