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.
