Initial Roentgenographic Manifestations of Pulmonary Mycobacterium Tuberculosis, M Kansasii, and M Intracellularis Infections

CT findings of pulmonary non-tuberculous mycobacterial infection in non-AIDS immunocompromised patients: a case-controlled comparison with immunocompetent patients

“…It has been reported that the upper lobe cavitary and the nodular bronchiectatic forms are responsible for most NTM infections in immunocompetent patients [19][20][21][22][23][24]. The cavitary form is usually seen in older, white males with underlying chronic pulmonary disease.…”

Nontuberculous Mycobacterium Infections in Rheumatoid Arthritis Patients

“…Cavitary disease is often seen in older men with substantial smoking histories and chronic PD (e.g., COPD, pneumoconiosis, prior TB, and sarcoidosis) (Bandoh et al, 2004;Christensen et al, 1981;Dhillon & Watanakunakorn, 2000;Fowler et al, 2006;Glassroth, 2008;Morita et al, 2005;Sonnenberg et al, 2000;Teosk & Lo, 1992;Wickremasinghe et al, 2005;Witly et al, 1994). Cavitary disease associated with NTM mostly occurs in the apical and posterior segments of the upper lobe, although multiple lung segments may be involved.…”

“…Cavitations typically include thick walls and no air-fluid level, and are often associated with pleural thickening, which is more extensive than that seen in TB. However, pleural effusion and substantial lymph node enlargement are less common than in TB (Albelda et al, 1985;Christensen et al, 1981;Reich & Johnson, 1991;Woodring et al, 1987) (Fig. 1).…”

CT Findings of Mycobacterium Avium Intracellulare Infections in the Lung

“…The appearances of MAI lung disease on chest radiography were considered indistinguishable from those owing to Mycobacterium tuberculosis (5,6). In 1989 Prince et al (3) were the first to recognize MAI infection in patients without pre-existing lung disease.…”
