RADIATION DIAGNOSIS OF COVID-19 IN PATIENTS WITH INTERSTITIAL LUNG DISEASE

Abstract

Purpose of the study. To assess the possibility of detecting COVID-19 radiation patterns in interstitial lung disease (ILD). Materials and methods. The results of the examination of 24 patients with ILD admitted to the St. Petersburg State Medical University named after I.I. acad. I.P. Pavlova from March 2020 to January 2021 about the addition of a new coronavirus infection. Patients with ILD were divided into 3 groups: 9 patients with progressive pulmonary fibrosis (PLF), 10 with sarcoidosis, and 5 with cystic lung lesions. In all patients, the diagnosis of ILD was confirmed morphologically, COVID-19 - by PCR. The average age of the patients was 47.4 ± 13.2 years (f/m - 13/11). Results. In patients with PLF, manifestations of COVID-19 were indistinguishable from idiopathic flare ups. The radiation pattern of patients with sarcoidosis, with the addition of COVID-19, was characterized by a combination of patterns of exacerbation of the underlying disease and the addition of COVID-19. Patients with cystic processes in the lung tissue showed signs of interstitial edema and the subsequent formation of postcovid fibrous changes in the lung tissue. Conclusions. The accumulation of experience in clinical and radiation examination of patients with a combination of various interstitial lung diseases - acute interstitial pneumonia (AIP) of an infectious nature (COVID-19) and primary interstitial lung disease, will make it possible to develop a radiation algorithm for their assessment, which is important for determining treatment tactics.
