COVID-19: a review of the literature and the experience of INMI Lazzaro Spallanzani two months after the epidemic outbreak

COVID-19 disease often presents as an acute respiratory syndrome with a very varied and still nonspecific radio-logical signs. The characteristic radiological signs begin to be known and codified and include the ground glass opacities in the initial phase of the disease, which are complicated by the thickening of the inter lobar and intra lobular septa with a “crazy paving” paintings, the appearance of areas of parenchymal consolidation up to full-blown acute respiratory distress syndrome states. The purpose of this paper is to review the international literature and the analysis of the first 70 patients studied at the National Institute for Infectious Diseases Lazzaro Spallanzani in Rome.
