CT features of pulmonary Mycobacterium avium complex infection.

摘要: OBJECTIVE The purposes of this study were to describe and compare the prevalence disease features in subjects with Mycobacterium avium complex (MAC) those tuberculosis infection (MTB), abilities CT chest radiography identify MAC disease, determine if sputum positivity is related any disease. METHODS Computed tomographic scans 15 MTB 55 reviewed by 2 observers. Sputum culture results (obtained within 1.9 +/- 2.8 days scanning) available 50 MAC. RESULTS Bronchiectasis involving four or more lobes (often associated centrilobular nodules) was seen only combination right middle lobe lingular bronchiectasis (p = 0.015). Thirty-one 34 (91%) who had cavities on a positive 3 weeks CT, compared 7 12 (58%) without 0.001). Similarly, 36 42 (85%) airspace but 8 (25%) grew mycobacteria from their sputa < not presence 0.156) nodules 0.377). CONCLUSION A subgroup patients may be distinguished widespread bronchiectasis, particularly it involves lingula. Cavities opacification are cultures for
