middle ear granulation tissue
Development of granulation tissue in the middle ear cavity is a generalized response to injury/inflammation, chronic otomastoiditis. It can either be typical or go down the pathway of becoming a cholesterol granuloma.
Radiographic features
Typical granulation tissue is common, more so than cholesterol granuloma, and has appearances in keeping with granulation tissue anywhere:
CT
Appears as soft tissue attenuation with mild enhancement on contrast administration.
MRI
Appears isointense on T1WI and bright contrast enhancement.
