Tuberculosis Coalescent Mastoiditis: A Report of Two Rare Cases.

Tuberculous otomastoiditis is a rare disease. Diagnosis generally occurs late when the patient already has irreversible sequelae. Two cases are reported with an unusual presentation of coalescent mastoiditis caused by Mycobacterium tuberculosis. The patients underwent several antibiotic treatments without clinical improvement, evolving temporal bone erosion and severe/profound hearing loss. Maintaining a high degree of suspicion regarding this clinical entity is important to obtain an early diagnosis, contributing to better care for these patients and avoiding serious complications.
