The Features of the Radiological Image of Community-Acquired Pneumonia at Interstitial Lung Diseases

Abstract

Community-acquired pneumonia (CAP) in patients with interstitial lung diseases is a terrible complication and has an atypical course. Diagnosis of CAP is difficult, since the clinical symptoms of inflammation are similar to those of ILD. The results of radiation studies are not pathognomonic, they are not always correctly interpreted, which leads to errors in diagnosis, delay in the examination and treatment of the patient. Aims: to evaluate the possibilities of CT in the detection and differential diagnosis of pneumonia in patients with ILD. Material and methods. The results of a complex clinical and radiological studies of 336 patients with IZL, 48 patients showed infiltrative changes in the lungs that were not characteristic of the main process. Results. Nonspecific inflammatory changes in the lung tissue were manifested by the following CT symptoms: alveolar type with local infiltration of the lung tissue corresponding to the segmental structure of the lungs (segment, lobe), the appearance of peribronchial alveolar type lung tissue that is not characteristic of radiation semiotics of the underlying disease. Conclusions: рerforming CT and VRKT reveals the appearance of infiltrative and focal changes that are atypical for IL, characteristic of specific and non-specific inflammatory processes, which affects the treatment tactics of patients.
