| 3 | Typical and atypical COVID-19 computed tomography findings显示文摘In December 2019 a novel coronavirus,named severe acute respiratory syndrome coronavirus 2 was identified and the disease associated was named coronavirus disease 2019(COVID-19).Fever,cough,myalgia,fatigue associated to dyspnea represent most common clinical symptoms of the disease.The reference standard for diagnosis of severe acute respiratory syndrome coronavirus 2 infection is real time reverse-transcription polymerase chain reaction test applied on respiratory tract specimens.Despite of lower specificity,chest computed tomography(CT),as reported in manifold scientific studies,showed high sensitivity,therefore it may help in the early detection,management and follow-up of COVID-19 pneumonia.Patients affected by COVID-19 pneumonia usually showed on chest CT some typical features,such as:Bilateral ground glass opacities characterized by multilobe involvement with posterior and peripheral distribution;parenchymal consolidations with or without air bronchogram;interlobular septal thickening;crazy paving pattern,represented by interlobular and intralobular septal thickening surrounded by ground-glass opacities;subsegmental pulmonary vessels enlargement(>3 mm).Halo sign,reversed halo sign,cavitation and pleural or pericardial effusion represent some of atypical findings of COVID-19 pneumonia.On the other hand lymphadenopathy’s and bronchiectasis’frequency is unclear,indeed conflicting data emerged in literature.Radiologists play a key role in recognition of high suspicious findings of COVID-19 on chest CT,both typical and atypical ones.Thus,the aim of this review is to illustrate typical and atypical CT findings of COVID-19. | Damiano Caruso Tiziano Polidori Gisella Guido Matteo Nicolai Benedetta Bracci Antonio Cremona MartaZerunian Michela Polici Francesco Pucciarelli Carlotta Rucci Chiara De Dominicis Marco Di Girolamo Giuseppe Argento Daniela Sergi Andrea Laghi | 2020 | World Journal of Clinical Cases2020，8，15： | 0 |
