Evolution of cavity formation in nontuberculosis mycobacteriosis of the lungs

The results of a long - term observation from practice are presented, which showed the gradual formation of the destruction cavity in a patient with limited focal and peribronchial fibrosis of the lung tissue. Patient H., 54 years old for more than twenty years, was observed by a pulmonologist at the place of residence with a diagnosis of chronic bronchitis with frequent annual exacerbations. She was admitted to the clinic of the FSBSI "CRIT" with complaints of pronounced weakness, fatigue, shortness of breath, prolonged subfebrile temperature mainly at night, cough with difficult-to-separate mucus of a mucous nature. A retrospective analysis of computed tomography of the chest revealed a consistent transformation of local focal peribronchial compaction in the middle lobe of the right lung into a limited area of bronchiectasia and the formation of a small cystic cavity with widespread zones of bilateral pneumonic infiltration. This observation shows the practical significance of CT research in understanding the mechanisms of formation of bronchiectatic cystic cavity in non-tuberculosis mycobacteriosis of the lungs.
