History of right ear cholesteatoma and surgery in 2000 and 2013: right ear fullness, right tympanic membrane retraction. There are postoperative findings related to right mastoidectomy, which contains fluid. There is diffuse mucosal enhancement along the walls of the mastoid bowl. However, there is no corresponding restricted diffusion in this region. The bilateral cranial nerve 7 and 8 complexes are intact. There is no evidence of mass lesions. The inner ear structures, including the cochlea, vestibule, endolymphatic duct, and semicircular canals, appear unremarkable. There is scattered mucosal enhancement and fluid within the left mastoid air cells and middle ears also appear unremarkable. There is a retention cyst in the right sphenoid sinus.
1. Postoperative findings related to right mastoidectomy with associated effusion and perhaps inflammation, including granulation tissue perhaps, but no evidence of cholesteatoma.2. Findings suggestive of left otomastoiditis.
