Tuberculous otomastoiditis is an uncommon form of acute otomastoiditis that occurs secondary to tuberculosis infection, although its frequency is increasing as a result of greater population of immunocompromised patients.
Classically it is described as presenting with
- painless chronic otorrhea
- intact tympanic membrane
Increasingly a wide range of presentations are being recognized including:
- purulent discharge
- ossicular erosion
- aggressive tumor-like behavior
Pachymeningeal involvement is also frequently seen with potential dural sinus thrombosis.
