Case ReportHistory
Exam
Prior Study
Findings
Extracranial Structures
There is no edema/cellulitis surrounding the pinna, periauricular soft tissues, parotid gland or masticator and parapharyngeal spaces on either side.
Right Temporal Bone
External auditory canal is filled with mucosal thickening but is not eroded.
There is middle ear or mastoid mucosal disease/fluid; these changes fill the middle ear cavity and mastoid antrum and few periantral air cells that are present. The mastoid septae are eroded, probably chronically, and there is dense sclerosis of the mastoid portion of the temporal bone consistent with chronic mastoiditis and likely cholesteatoma. The roof of the mastoid and middle ear are not eroded.
The malleus and incus are demineralized the stapes is not visible.
The sigmoid plate of the mastoid is eroded. There is a subperiosteal and/or epidural abscess along the sigmoid plate of the mastoid displacing the adjacent sigmoid sinus.
The facial canal is not intact; this may be due to erosion or just be a normal anatomic variation.
The inner ear, in particular the lateral semicircular canal and the cochlea are normal.
Left Temporal Bone
There are no significant abnormalities of the left temporal bone.
Intracranial
There is no significant intracranial infectious or vascular complication other than a likely localized epidural abscess along the sigmoid plate described previously. There is no evidence of hydrocephalus or meningitis. Imaging studies cannot exclude meningitis.
