Coronavirus disease 2019 (COVID-19) represents a very heterogeneous disease. Some aspects of COVID-19 pneumonia question the real nature of ground glass opacities and its consolidative lesions. It has been hypothesized that COVID-19 lung involvement could represent not only a viral effect but also an immune response induced by the infection, causing epithelial/endothelial lesions and coagulation disorders. We report 3 cases of COVID-19 pneumonia in which contrast-enhanced ultrasound was suggestive of consolidations with perfusion defects, at least in part caused by ischemic or necrotic changes and not only by inflammatory or atelectasis events.
2019 冠状病毒病(COVID-19)表现为一种非常异质性的疾病。COVID-19 肺炎的某些方面引发了对磨玻璃密度及其实变病变的真正性质的质疑。有人假设,COVID-19 肺部受累不仅可能是病毒的作用,而且可能是感染引起的免疫反应,导致上皮/内皮损伤和凝血障碍。我们报告了 3 例 COVID-19 肺炎病例,其中增强超声提示存在实变伴灌注缺损,至少部分是由缺血或坏死改变引起的,而不仅仅是由炎症或肺不张事件引起的。
