The COVID-19 has been confirmed to spread from person to person, mainly transmitting through respiratory secretions or direct contact. At present, the diagnosis of COVID-19 pneumonia is based on clinical symptoms, contact history of epidemic area, imaging diagnosis, and nucleic acid detection. However, false negative in nucleic acid detection has been reported, and the clinical symptoms may be atypical that may cause misdiagnosis and make the situation spread. Therefore, the imaging examination becomes particularly important [1]. Incubation period for COVID-19 is usually is 3-7 days, but not more than 14 days, contamination occurs during the incubation period. The main symptoms are increased increase in body temperature (above 38 C), weakness, dry cough and diarrhea. Several complications of COVID-19 have been described, which includes acute respiratory distress syndrome, arrhythmias, acute cardiac injury and shock [2] thromboembolic complications [3], cytokine storm syndrome, liver injury, renal insufficiency and multiple organ dysfunction syndrome [4]. In addition, COVID-19 is viral pneumonia, acute respiratory distress syndrome and respiratory failure with risk of death [5]. In about 15% of cases, the disease proceeds in severe form with the need to use oxygen therapy, in 5% the condition of patients is critically ill. The lethality of the disease is estimated by an example but at 2.3%. According to the analysis of 1099 patients as of February 28, 2020, 91.1% of patients with COVID-19 were diagnosed with pneumonia [6]. Severe condition of patients, manifestation of pulmonary symptoms of damage (cough, shortness of breath) and a high likelihood of viral pneumonia with COVID-19 led to a rapid and repeated CT scans in this group patients, which made it possible to identify the primary signs of diseases, their subsequent transformation and the most unfavorable radiologic symptoms, corresponding to the difficult course of the process.
