Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can affect the nervous system and result in neurological symptoms. The most common feature of central nervous system involvement is hypoxia and congestion. This study aimed to evaluate the histopathology of cerebral tissue in deceased patients with coronavirus disease 2019 (COVID-19).
Methods: In a case series study, we took cerebral samples of 30 deceased patients with COVID-19 through supraorbital bone from January to May 2021. The samples were fixed in a formalin solution, stained with haematoxylin-eosin dyes and studied by two expert pathologists. The Ethics Committee of AJA University of Medical Sciences approved this study with code IR.AJAUMS.REC.1399.030.
Results: The mean age of the patients was 73.8 years, and the most common underlying disease was hypertension. Cerebral tissue samples showed hypoxic-ischaemic changes in 28 (93.3%), microhaemorrhage in six (20%), lymphocytic infiltration in five (16.7%) and thrombosis in three samples (10%).
Conclusion: Hypoxic-ischaemic change was the most common neuropathology in our patient. Our study showed that many patients with severe COVID-19 may develop central nervous system involvement.
