Abstract
A case of an 8-month-old boy with atypical Mycobacterial otitis media is reported. Initially it was thought to be acute otitis media with effusion, but afterwards was suspected to be Mycobacterium tuberculosis otitis media. Cultures for acid-fast bacilli reveadled a Mycobacterium species. Sections of tissue for Ziel-Nielsen stain also showed acid-fast bacilli. An negative Niacin test established the diagnosis as atypical mycobacterial infection. It was treated with attico-mastoidectomy and isonicotinic acid hydrazine (INAH) administration. There have been only three cases of atypical mycobacterium otitis media so far reported in the English literature, but none in Japanese.
