“…A second patient was reported by Wary et al; this patient presented with hoarseness, fever, and pulmonary symptoms for 1 week. Mycobacterium kansasii was isolated from a sputum specimen, and the hoarseness resolved with treatment for M. kansasii . The third patient was diagnosed with pulmonary M. kansasii and then developed a laryngeal inflammatory pseudotumor secondary to M. Kansasii .…”

Chronic laryngitis commonly presents with dysphonia, and infectious causes include tuberculosis and endemic mycoses. We present a 58-year-old female with laryngitis for 5 years, fevers, chills, fatigue, malaise, myalgias, anterior neck pain, and night sweats after multicontinent exposure. Bronchoscopy cultures were negative. Bilateral microflap excision of vocal fold lesions demonstrated thickened epithelium and a deep vocal fold mass. Biopsy showed necrotizing granulomatous inflammation with acid-fast bacilli. Mycobacterium kansasii was identified. Treatment led to improvement in dysphonia, systemic symptoms, and vocal fold irritation. To our knowledge, this is the first case of isolated nontuberculous mycobacterial vocal fold infection.

Nontuberculous Mycobacterial Otomastoiditis: A Case Report

et al. 2013

View full text Add to dashboard Cite

Nontuberculous mycobacterial otomastoiditis is rare and can be easily confused with various different forms of otitis media. We describe the case of a 50-year-old woman who presented with left-sided chronic otitis media that had persisted for more than 1 year. It was not eradicated by standard antimicrobial therapy and surgical debridement. After appropriate antibiotic therapy for nontuberculous mycobacteria was added to the therapeutic regimen, the patient improved significantly and the lesion had healed by 6 months. Based on our experience with this case, we conclude that early bacterial culture and staining for acid-fast bacilli in ear drainage material or granulation tissue should be performed when standard antimicrobial therapy fails to eradicate chronic otitis media of an undetermined origin that is accompanied by granulation tissue over the external auditory canal or middle ear. Polymerase chain reaction testing is also effective for rapid diagnosis. Surgical debridement and removal of the foreign body can successfully treat nontuberculous mycobacterial otomastoiditis only when effective antimicrobial therapy is also administered.

Hoarseness due to Mycobacterium kansasii

Abstract: There are many causes of unilateral vocal fold paralysis. This case illustrates the importance of anatomical knowledge in reaching a diagnosis, and also presents the first reported case of Mycobacterium kansasii creating this clinical picture.
