“…Previous studies have shown that the lobe involvement was most frequently distributed along the bronchovascular bundles or subpleural regions in the bilateral lungs (6)(7)(8), which is consistent with the CT findings in the two cases that we reported. However, not all of the patients with COVID-19 had abnormal CT features.…”

“…(8/10, 80%) patients with lesions involving 4 to 5 lobes distributed peripherally or subpleural regions, the most significant lesions were observed in the bilateral lower lobes, especially in the right lower lobe (9/10, 90%). Previous studies shown that the most frequency of lobe involvement was located in bilateral lower lobe [16,18,19], especially located in the right lower lobe [16,19,20]. Therefore, we speculated that involvement of lower lobes (the particular involvement of right lower lobe) were the relative specific sign for the radiologists to know in the patients with COVID-19 pneumonia (Fig.…”

OBJECTIVE: To evaluate the clinical and computed tomographic (CT) features in the patients with COVID-19 pneumonia confirmed by the real-time reverse transcriptase polymerase chain reaction (rRT-PCR) amplification of the viral DNA from a sputum sample. MATERIAL AND METHODS: Clinical information and CT findings of a total of 14 patients with COVID-19 infection (age range, 12-83 years; females 6) were analyzed retrospectively. The clinical information includes the history of exposure, laboratory results, and the symptoms (such as fever, cough, headache, etc.); CT findings of chest include the extension and distribution of lesion, the ground-glass opacity (GGO), consolidation, bronchovascular enlarged, irregular linear appearances, pleural effusion, and lymphadenopathy. RESULTS: Eight patients had the exposure history for recent travel to Wuhan of Hubei province (8/14, 57%), 6 had the exposure to patients with COVID-19 infection. Significant statistical differences were observed in lymphocyte percentage decreased and C-reactive protein elevated (p = 0.015). Seven patients had fever, 7 had cough, 2 had headache, 3 had fatigue, 1 had body soreness, 3 had diarrhea, and 2 had no obvious symptoms. In chest CT examination, 10 patients were positive (10/14, 71.43%). Among these patients, 9 had lesions involving both lungs (9/10, 90%), 8 had lesions involving 4 to 5 lobes (8/10, 80%). Most of lesions were distributed peripherally and the most significant lesions were observed in the right lower lobe in 9 patients (9/10, 90%). Nodules were observed in 5 patients (5/10, 50%); GGO, consolidation, and bronchovascular enlarged were shown in 9 patients (9/10, 90%); irregular linear appearances were revealed in 7 patients (7/10, 70%); and pleural effusions were exhibited in 2 patients (2/10, 20%). Last, no patients showed lymphadenopathy. CONCLUSION: There were some typical CT features for diagnosis of COVID-19 pneumonia. The radiologists should know these CT findings and clinical information, which could help for accurate analysis in the patients with 2019 novel coronavirus infection.

“…Several recent studies (Chan et al, 2020;Chen et al, 2020;Chung et al, 2020;Kanne, 2020;Koo et al, 2018;Lei et al, 2020;Liu and Tan, 2020;Pan and Guan, 2020;Song et al, 2020;Wang et al, 2020) have described common chest imaging findings of lung pathology caused by SARS-COV2. The imaging findings recently reported in patients with COVID-19 appear similar to those reported with SARS-CoV (Ooi et al, 2004;Nestor et al, 2004;Nicolaou et al, 2003) and MERS-CoV (Das et al, 2015a;Das et al, 2015b) infection.…”

Introduction: Several recent case reports have described common early chest imaging findings of lung pathology caused by 2019 novel Coronavirus (SARS-COV2) which appear to be similar to those seen previously in SARS-CoV and MERS-CoV infected patients. Objective: We present some remarkable imaging findings of the first two patients identified in Italy with COVID-19 infection travelling from Wuhan, China. The follow-up with chest X-Rays and CT scans was also included, showing a progressive adult respiratory distress syndrome (ARDS). Results: Moderate to severe progression of the lung infiltrates, with increasing percentage of high-density infiltrates sustained by a bilateral and multi-segmental extension of lung opacities, were seen. During the follow-up, apart from pleural effusions, a tubular and enlarged appearance of pulmonary vessels with a sudden caliber reduction was seen, mainly found in the dichotomic tracts, where the center of a new insurgent pulmonary lesion was seen. It could be an early alert radiological sign to predict initial lung deterioration. Another uncommon element was the presence of mediastinal lymphadenopathy with short-axis oval nodes. Conclusions: Although only two patients have been studied, these findings are consistent with the radiological pattern described in literature. Finally, the pulmonary vessels enlargement in areas where new lung infiltrates develop in the follow-up CT scan, could describe an early predictor radiological sign of lung impairment.
