is accompanied by facial weakness, pain and hearing difficulties.
Herein I describe a patient with petrositis (or mastoiditis) but with no frequently presenting MRI features of RHS.
Petrositis has also been associated with a poor antiviral treatment response.
Petrositis in Ramsay Hunt syndrome with multiple cranial neuropathies.
Extracranial complications of acute otomastoiditis include mastoiditis with bone destruction, subperiosteal abscess, petrositis
, facial nerve paralysis, and labyrinthitis; intracranial complications include meningitis, perisinus abscess, brain abscess, subdural abscess, extradural abscess, lateral sinus thrombosis or thrombophlebitis, and otitic hydrocephalus.
We evaluated a 57-year-old woman who developed symptoms consistent with apical petrositis on the right.
Apical petrositis can be acute or chronic, and it can be the result of an infection of the middle ear to the pneumatized air cells of perilabyrinthine and apex of the temporal bone.
It is a matter of debate as to whether apical petrositis always occurs in the pncumatized apex because petrositis has also been described in the nonpneumatized apex, probably secondary to a hematogenously spread infection.
5) Labyrinthitis and petrositis
have also been reported in association with the mastoid disease.
Effusions can be mistaken for a cholesterol granuloma and petrositis
, and asymmetric fatty marrow can be mistaken for a cholesteatoma.
