Is this the same reason why so many mri reports show mastoiditis even though patinet has no signs or symptoms?

[@ENT_Imaging]

Radiologists overuse the term "mastoiditis". Unless you see enhancement in the walls of the air cells, you cannot be sure that it is inflamed. Sub-total filling of the mastoid air cells is most often bland effusion. I suggest the diagnosis of otomastoiditis only when I see complete filling of the middle ear cavity and mastoid air cells (or when I see mucosal enhancement on MRI).
