Both the ongoing severe acute respiratory syndrome-related coronavirus 2 pandemic and increasing number of survivors after coronavirus disease 2019 (COVID-19) state new challenges. One of them is proper assessment after infection in order to safe return to professional, physical and social activity and avoidance of undiagnosed, potentially life-threating complications. Significant element is a choice of diagnostic methods for evaluation of the parenchymal changes within the lungs. Despite high resolution computed tomography is still a gold standard, the use of lung ultrasonography is still increasing. It is a complementary diagnostic method which might be performed simultaneously with echocardiography. We present the proposition of use lung ultrasound in a 34-year-old patient, elite athletes- trainer after COVID-19, who developed parenchymal lung changes and recovered from them in a short time interval.
