Abstract

AbstractPurpose:Otomastoiditis is a rare but important manifestation of tuberculosis and is well recognizable when information on its clinical course is considered in connection with the radiographic changes.Material and Method:A patient with a clinical history of chronic otorrhea, resistant to conventional therapy but without dramatic symptoms, was referred for CT examination.Results:CT revealed widespread soft tissue densities in the tympanic cavity and in the mastoid process, with bone erosions in the latter. Surgery and bacteriology confirmed the diagnosis of Mycobacterium tuberculosis infection.Conclusion:CT evidence of widespread bone destruction without clinical signs of aggressive infection should suggest the diagnosis of a mycobacterial process. Early treatment is essential in order to avoid propagation of the disease and lasting loss of function.
