Objective: To study the dynamic changes in CT findings in COVID-19 (coronavirus disease-19, COVID-19) rehabilitated patients. Methods: A total of 148 chest CT images of 37 patients with COVID-19 were collected. In the first 21 days of the course of disease, 7 stages were performed every 3 days, and the eighth stage was performed after 21 days. Results: In the first chest CT examination, 19 cases were ground glass opacity, and 18 cases were high-density shadows with consolidation. The lesion shape was flaky and patchy in 33 cases. The percentage of consolidation, air bronchogram, fiber cord, interlobular septal thickening, subpleural line and pleural thickening were the highest on days 4-6, 7-9, 7-9, 10-12, 19-21 and 19-21, respectively. The highest percentage of disease progression was 80.00% on days 4-6, and then the percentage of disease progression gradually decreased with the extension of the onset time. The percentage of patients with improvement gradually increased from days 4-6, reaching 83.33% on days 16-18 and 100.00% on day 21. The percentage of lesion range enlargement and density increase was the highest on days 4-6, both of which were 60.00%，Then the percentage of both decreased gradually. The percentage of patients with lesion range reduction and density absorption dilution increased gradually with the onset time. There was no obvious regularity in the number of lesions. Conclusion: Patients with COVID-19 have regular changes in their lung conditions.

Background: Novel coronavirus disease (COVID-19) pneumonia is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is highly contagious and threatens human health. Chest computed tomography (CT) is an accurate imaging modality for diagnosis and follow-up. Objectives: To investigate early CT features of COVID-19 pneumonia. Methods: Retrospective study. Sixty-three patients with COVID-19 pneumonia (28 men, 35 women; age range, 21 - 85 years; mean, 59 years) confirmed by reverse transcription-polymerase chain reaction (RT-PCR) were enrolled in this retrospective study and CT findings were evaluated. Patients were classified into three groups for estimating COVID-19 pneumonia, according to CT features. Results: Nineteen (30%) patients classified as out of COVID-19 pneumonia had normal CT findings. Twenty-eight (44%) patients, classified as highly suggestive for COVID-19 pneumonia, had typical findings for COVID-19 pneumonia. In highly suggestive for COVID-19 pneumonia group most common CT features were peripheral (64%), multilobar (96%), patchy, and round (54%) ground-glass opacity (GGO) (57%). Air bronchogram (93%), crazy-paving patterns (79%), and vascular thickening (61%) were the most common special findings. We only detected these rare findings such as halo sign, reverse halo sign, lymphadenopathy, pleural and pericardial effusion, pleural thickening, and fibrotic lines in patients with COVID-19 with chronic diseases. Conclusions: The early CT findings are peripheral, multilobar, patchy, and round ground glass opacities accompanied by vascular thickening, crazy-paving pattern, or air bronchogram sign. Rare findings are only seen in the presence of concomitant diseases.

Background. CT plays a valuable role in assessment of patients with a wide variety of diseases of the pleura, and pulmonologists should be aware of the significance of different CT findings for the differential diagnosis of benign and malignant pleural diseases. Methods. 155 patients with pleural disease who had undergone CT scans of the lungs and thorax before treatment were enrolled. We retrospectively reviewed CT findings in 146 patients with proven pleural disease. Results. Fifty-nine of the cases were malignant, 87 of them had benign pleural diseases. CT findings that were helpful in distinguishing malignant from benign pleural disease were: 1) pleural nodularity; 2) rind; 3) mediastinal pleural involvement; and 4) pleural thickening greater than 1 cm. The sensitivities and specificities were 37%/97%, 22%/97%, 31%/85%, 35%/87%, respectively. CT findings differentiating malignant pleural mesothelioma from metastatic pleural disease were identified. Findings for malignant mesothelioma were as follows: 1) involvement of interlobar fissure (sensitivity 30%, specificity 92%), 2) pleural thickening greater than 1 cm (sensitivity 60%, specificity 77%). Whereas, findings for metastatic pleural disease were mediastinal/hilar lymph node enlargement and lung parenchymal involvement (P<.05). Conclusion. CT is helpful in the differential diagnosis of pleural diseases, particularly in differentiating malignant from benign conditions and metastatic pleural disease from malignant mesothelioma.

Objective. The COVID-19 pandemic and annual influenza epidemic are responsible for thousands of deaths globally. With a similarity in clinical as well as laboratory findings, there is a need to differentiate these two conditions on chest CT scan. This paper attempts to use existing literature to draw out differences in chest CT findings in COVID-19 and influenza. Methods. A search was conducted using PubMed. 17 original studies on chest CT findings in COVID-19 and influenza were identified for full-text review and data analysis. Findings. COVID-19 and influenza share similar chest CT findings. The differences found show that COVID-19 ground-glass opacities are usually peripherally located with the lower lobes being commonly involved, while influenza has a central, peripheral, or random distribution usually affecting the five lobes. Vascular engorgement, pleural thickening, and subpleural lines were reported in COVID-19 patients. In contrast, pneumomediastinum and pneumothorax were reported only in studies on influenza. Conclusion and Relevance. COVID-19 and influenza have overlapping chest CT features with few differences which can assist in telling apart the two pathologies. Additional studies are needed to further define the differences and degree between COVID-19 and influenza.

Abstract Background : Recently, the World Health Organization (WHO) has declared the coronavirus disease 2019 (COVID-19) outbreak a public health emergency of international concern. So far, however, limited data are available for children. Therefore, we aimed to investigate the clinical and chest CT imaging characteristics of COVID-19 in preschool children. Methods: From January 26, 2020 to February 20, 2020, the clinical and initial chest CT imaging data of eight preschool children with laboratory-confirmed COVID-19 from two hospitals were retrospectively collected. The chest CT imaging characteristics, including the distribution, shape, and density of lesions, and the pleural effusion, pleural changes, and enlarged lymph nodes were evaluated. Results: Two cases (25%) were classified as mild type, and they showed no obvious abnormal CT findings or minimal pleural thickening on the right side. Five cases (62.5%) were classified as moderate type. Among these patients, one case showed consolidation located in the subpleural region of the right upper lobe, with thickening in the adjacent pleura; one case showed multiple consolidation and ground-glass opacities (GGO) with blurry margins; one case displayed bronchial pneumonia-like changes in the left upper lobe; and two cases displayed asthmatic bronchitis-like changes. One case (12.5%) was classified as critical type and showed bronchial pneumonia-like changes in the bilateral lungs, presenting blurred and messy bilateral lung markings and multiple patchy shadows scattered along the lung markings with blurry margins. Conclusions: The chest CT findings of COVID-19 in preschool children are atypical and various. Accurate diagnosis requires a comprehensive evaluation of epidemiological, clinical, laboratory and CT imaging data.

Abstract OBJECTIVESCT findings of COVID-19 infected patients has been well described, but it it’s roll in depicting signs of fibrosis in critically ill patients remains unclear. To our knowledge, there are no radiopathological correlations of the pulmonary pathology. Exudative and proliferative diffuse alveolar damage (DAD) are the most commonly reported injury. Few studies describe fibrosis, the last phase of DAD. Our study correlates post-mortem chest US and CT findings of COVID-19 infected patients with the histopathology from biopsies taken of the lung. It focuses on the role of CT to depict fibrosis. METHODSThis is a prospective observational study of six consecutive deceased patients infected with COVID-19. Post-mortem chest CTs and US were performed within 24 hours of death. CT and US were used to obtain biopsies of different radiological patterns. Pre-mortem CT examinations were also retrospectively evaluated. RESULTSOn CT, all patients presented with extensive areas of consolidation and ground-glass opacities affecting most segments of the lung. Pleural effusion was present in all cases. Four of the patients showed signs of fibrosis. On US, subpleural consolidation, pleural thickening, and B-pattern were present.All patients showed different stages of DAD, mostly proliferative DAD. Four patients presented with fibrotic DAD, all of which had been admitted for over three weeks and correlated with the CT findings of fibrosis. CONCLUSIONIn our study, signs of fibrosis on CT show a histopathological correlation. CT may be useful to identify the group of COVID-infected patients that develop fibrosis as a marker of poor prognosis, in the late stage of the disease.
