Features of radiological manifestations in the diagnosis of nontuberculous mycobacteriosis. Literature review Сlinical observation

Abstract

Purpose of the study. The purpose of this literature review is to determine the radiographic features in the diagnosis of non-tuberculous mycobacteriosis (NTMB) and to assess the possibility of radiological diagnosis of a combination of tuberculosis and non-tuberculous mycobacteriosis of the lungs in a patient with HIV infection.Materials and methods. A review of the literature on the bases of scientific articles PubMed, ELibrary and Google Scholar. Attention was focused on full-text articles. The article presents a clinical observation of a patient being treated at the Clinical TB Dispensary in Omsk from 2019 to 2022 with a diagnosis of disseminated pulmonary tuberculosis, bilateral, in the infiltration phase, tuberculous spondylitis ThVII–IX, complicated by a paravertebral abscess.Results. The radiological changes characteristic of NTMB are: lesion of the right middle and lingual lobes of the lungs with the presence of diffuse bronchiectasis, changes in the type of “tree in the kidneys”, compaction of lung tissue by the type of “frosted glass” with the presence of centrilobular nodules, asymmetric small dense foci with peribronchial location, apical location of thin-walled cavities with thickening of the costal pleura, as well as foci of inflammatory infiltration. The absence of specific symptoms for this pathology requires further research in this area. The identification of characteristic radiological features will speed up the diagnosis of infection and determine the correct management tactics for patients.Conclusion. The radiosemiotics of NTMB is characterized by a large variability of manifestations. The most informative method of radiation diagnosis of NTMB is multispiral computed tomography (MSCT). Thanks to MSCT, a radiologist has the opportunity to accurately assess the localization and nature of foci, as well as assess the dynamics and prevalence of the process. The most characteristic radiological symptoms are the defeat of the right middle and lingual lobes of the lungs with the presence of diffuse bronchiectasis, changes in the type of “tree in the kidneys”, compaction of lung tissue by the type of “frosted glass” and the presence of centrilobular nodules, asymmetric small dense foci with peribronchial arrangement, apical arrangement of thin-walled cavities with thickening of the costal pleura, as well as foci inflammatory infiltration. The absence of specific symptoms for this pathology requires further research in this area. The identification of characteristic radiological features will speed up the diagnosis of infection and determine the correct management tactics for patients.
