Coronaviridae family includes pathogen viruses for humans, that lead to clinical conditions with main respiratory involvement; many of these viruses have notoriously a neuroinvasive potential, as demonstrated by published data on SARS‐CoV and MERS‐CoV epidemics, as well by results obtained in experimental models. During pandemic of coronavirus disease 2019 (COVID‐19), it is noticed that the central nervous system involvement represented a truly significant moment in the history of some COVID‐19 patients; indeed, clinical and radiological features published in literature regarding COVID‐19 disease are consistent with a neurological involvement. It is also known that histopathological data related to SARS‐CoV2 infection have been published with considerable delay, which was even greater for neuropathological information. Moreover, many published data are incomplete, and often the lesions described are not directly related to the action of the virus. In this review, we collected the available radiological and neuropathological information, in order to delineate a more complete picture of the relationship between SARS‐Cov2 and brain, focusing our attention on the two most important neuroinvasion routes for the virus. We also highlighted what we consider methodological mistakes both in the autopsy procedures and brain study in COVID‐19 deaths. We emphasize the need for a complete study of all the organs in case of autopsy. It is important that through this experience, we no longer do the mistake of neglecting the brain.

具有神经放射学和神经病理学发现的SARS-CoV2的神经侵袭潜力:大脑是目标还是受害者?

冠状病毒科包括人类的病原体病毒,可导致主要呼吸道疾病的临床症状。正如SARS-CoV和MERS-CoV流行病的公开数据以及在实验模型中获得的结果所证明的那样,其中许多病毒具有神经入侵的潜力。在2019年冠状病毒大流行期间(COVID-19),注意到中枢神经系统受累代表了某些COVID-19患者病史中一个真正重要的时刻; 实际上,文献中发表的有关COVID-19疾病的临床和放射学特征与神经系统疾病相一致。还众所周知,与SARS-CoV2感染有关的组织病理学数据已被大量出版,对于神经病理学信息而言甚至更大。此外,许多公开的数据不完整,通常所描述的病变与病毒的作用没有直接关系。在这篇综述中,我们收集了可用的放射学和神经病理学信息,以描绘出SARS-Cov2与大脑之间关系的更完整图景,并将我们的注意力集中在该病毒的两个最重要的神经入侵途径上。我们还强调了在尸检程序和脑部研究中COVID-19死亡中我们认为的方法学错误。我们强调有必要对尸体进行全面研究。重要的是,通过这种经验,我们不再犯忽略大脑的错误。我们收集了可用的放射学和神经病理学信息,以便更全面地描绘SARS-Cov2与大脑之间的关系,并将注意力集中在该病毒的两个最重要的神经入侵途径上。我们还强调了在尸检程序和脑部研究中COVID-19死亡中我们认为的方法学错误。我们强调有必要对尸体进行全面研究。重要的是,通过这种经验,我们不再犯忽略大脑的错误。我们收集了可用的放射学和神经病理学信息,以便更全面地描绘SARS-Cov2与大脑之间的关系,并将注意力集中在该病毒的两个最重要的神经入侵途径上。我们还强调了在尸检程序和脑部研究中COVID-19死亡中我们认为的方法学错误。我们强调有必要对尸体进行全面研究。重要的是,通过这种经验,我们不再犯忽略大脑的错误。我们还强调了在尸检程序和脑部研究中COVID-19死亡中我们认为的方法学错误。我们强调有必要对尸体进行全面研究。重要的是,通过这种经验,我们不再犯忽略大脑的错误。我们还强调了在尸检程序和脑部研究中COVID-19死亡中我们认为的方法学错误。我们强调有必要对尸体进行全面研究。重要的是,通过这种经验,我们不再犯忽略大脑的错误。
