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.
