RESUMEN
The article provided the information about the results of clinical-morphological analysis of the practical observation with pulmonary aspergillosis associated with COVID-19 and undiagnosed when the patient was alive. The pulmonary aspergillosis associated with COVID-19 is one of the widespread complications. However, in numerous cases, the pulmonary aspergillosis associated with COVID-19 is not diagnosed due to its unclear signs and lack of information about it. An infiltrate with signs of destruction was noted during X-ray examination of the lower part of the right lung of the observed patient. It was evaluated as destructive pneumonia associated with bacterial infection. However, despite the patient had type II diabetes, no additional examination methods were applied to exclude aspergillosis. Disruption of the protective properties of the bronchial epithelium and the effect of oseltamivir type drugs may also contribute to the entry of aspergillus fungi into the lung tissue. According to the authors, during the development of diagnosis, treatment and prevention strategy of COVID-19in the patients with pulmonary aspergillosis it is important to study the interaction of these diseases.Copyright © 2022 Authors.
