| description | Objective: to determine, evaluate, and describe different radiological patterns of microbiologically identified nontuberculous pulmonary mycobacterioses (NTPM) based on multislice computed tomography data. Material and methods. The study included 102 patients with radiological signs of lung disease and different types of NTPM. Slowly growing types of NTPM were detected in 62 (60.8 %) patients, and rapidly growing NTPM – in 40 (39.2 %). The diagnosis was established considering a patient’s complaints, a specified case history, radiological and clinical laboratory data including microscopic studies of sputum from 63 (61.8 %) patients, bronchoalveolar lavage and different types of bronchial biopsies data from 19 (18.6 %) patients, samples of lung video-assisted thoracoscopic surgery from 17 (16.7%) patients, pleural fluid samples from 2 (1.9 %) patients, and oropharyngeal wash samples from 1 (1 %) patient. We used the Somatom Emotion 16 multislice computed tomograph (Siemens) and the high-resolution algorithm (HRCT) with 0.8 mm slice thickness and 1.5 mm slice increment. Results. The HRCT data were highly polymorphic and showed interstitial focal changes, different calibre bronchiectasis, conglomerates or cavities, involvements of vessels or pleural layers. In some patients, changes in the axial interstitium were accompanied by single small focal consolidations located either discretely or in small groups. Peribronchovascular spread of dissemination foci in NTPM was detected by HRCT as irregular infiltration of the axial interstitium (vasculitis type). Changes in the bronchial tree in NTPM were characterized by bronchiolitis symptoms (extensive thickening of bronchial walls, bronchioles) with development of the tree-in-bud sign predominantly in the subpleural lung regions. In some cases, bronchiectatic changes formed conglomerate consolidations of sublobular or lobular extent. Changes of the bronchial tree were detected by HRCT predominantly as signs of deforming bronchitis, cylindrical, varicose, or cystic bronchiectasis, either restricted or spread. Changes might be accompanied by single multi-dimensional cystic bronchiectatic cavities. Conclusion. Typical HRCT signs of NTPM are endobronchial and peribronchovascular spread of foci, development of multi-dimensional conglomerates, deforming bronchitis, bronchiectasis, and presence of single multi-dimensional cystic bronchiectatic cavities. |
