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.
Typical granulation tissue is common, more so than cholesterol granuloma, and has appearances in keeping with granulation tissue anywhere:
- CT - soft tissue, mild enhancement
- MRI - isointense on T1WI and bright contrast enhancement.
