Pulmonary tuberculosis and Mycobacterium avium-intracellulare: a comparison of CT findings.

Abstract

Although CT findings of pulmonary tuberculosis and MAI are similar, interlobular septal thickening is more common in patients with tuberculosis and bronchiectasis is more common and more extensive in patients with MAI.

Serological test and chest computed tomography findings in patients with Mycobacterium avium complex lung disease

“…The combination of multiple small nodules on CCT with bronchiectasis, particularly in the middle lobe and/or lingual lobe, should suggest the diagnosis of MAC lung disease [10][11][12]. In the present study, the clinical background and laboratory findings, including GPL core antibody, were similar between the MAC disease group and the MAC-culture positive group.…”

Nontuberculous Mycobacterium Infections in Rheumatoid Arthritis Patients

“…2). Bronchiectasis is more commonly associated with NTM than in TB (Primack et al, 1995), with bilateral bronchiectasis and bronchiolitis occurring in one third of NTM patients, as detected by HRCT. However, the coexistence of bronchiectasis and bronchiolitis (i.e., centrilobular nodules and mosaic pattern) is also highly suggestive of NTM infection .…”

“…In fibronodular bronchiectasis, CT findings are characterized by small centrilobular nodules or tree-in-bud opacities, with cylindrical bronchiectasis typically detected in the same lobe (Han et al, 2003;Hartman et al, 2003;Moore, 1993;Obayashi et al, 1999;Primack et al, 1995;Swensen et al, 1994) (Fig. 2).…”

CT Findings of Mycobacterium Avium Intracellulare Infections in the Lung

“…Spiculation, pleural indentation could be seen at the nodules (23,24). Moore (25) examined CT scans of the chest from the patients with cultures positive for atypical mycobacteria.…”
