Chronic otomastoiditis with tympanosclerosis

Chronic otomastoiditis with tympanosclerosis represents calcific foci within the middle ear or tympanic membrane secondary to suppurative chronic otomastoiditis.

Pathology

Tympanosclerosis reflects deposits of hyalinized collagen in the tympanic cavity. It can manifest as unifocal or multifocal punctate or web-like calcifications in the middle ear cavity or on the tympanic membrane (myringosclerosis).

Radiographic features

Features include chronic otomastoiditis findings such as middle ear soft tissue density and under-pneumatized mastoid associated with calcifications. Common locations of calcifications include:

• tympanic membrane

• ossicle surface

• stapes footplate

• muscle tendons

• ossicle ligaments
