Abstract

The most common presentation of mycobacterial infection encountered in otolaryngological practice is cervical lymphadenitis. We report a child with an unusual cause of cervical lymphadenopathy, i.e. dual tuberculous infections. This had clinical ramifications as, initially Mycobacterium avium-intracellulare was grown in culture and was resistant to standard anti-tuberculous agents, and hence treated with excision of the lymph node. However, the cultures from the excised lymph node grew out Mycobacterium tuberculosis that was sensitive to standard anti-tuberculous drugs. To our knowledge, no such presentation has been reported previously. We also review the literature on cervical lymphadenitis due to atypical mycobacteria and Mycobacterium tuberculosis , with particular emphasis on clinical presentation, diagnosis and management.
