Abstract
Coronavirus Disease 19 (COVID-19) pandemic affects the worldwide healthcare system and our understanding of this disease grows rapidly. Although COVID-19 is a mainly respiratory disease, neurological manifestations are not uncommon. The aim of this review is to report on the etiology, clinical profile, location, and outcome of patients with intracerebral hemorrhage (ICH) and COVID-19. This review includes 36 studies examining ICH in the clinical presentation of COVID-19. Overall, 217 cases with intracranial hemorrhage, of which 188 ICHs, were reported. Generally, a low incidence of both primary and secondary ICH was found in 8 studies [106 (0.25%) out of 43,137 hospitalized patients with COVID-19]. Available data showed a median age of 58 years (range: 52-68) and male sex 64%, regarding 36 and 102 patients respectively. Furthermore, 75% of the patients were on prior anticoagulation treatment, 52% had a history of arterial hypertension, and 61% were admitted in intensive care unit. Location of ICH in deep structures/basal ganglia was ascertained in only 7 cases making arterial hypertension an improbable etiopathogenetic mechanism. Mortality was calculated at 52.7%. Disease related pathophysiologic mechanisms support the hypothesis that SARS-CoV2 can cause ICH, however typical ICH risk factors such as anticoagulation treatment, or admission to ICU should also be considered as probable causes. Physicians should strongly suspect the possibility of ICH in individuals with severe COVID-19 admitted to ICU and treated with anticoagulants. It is not clear whether ICH is related directly to COVID-19 or reflects expected comorbidity and/or complications observed in severely ill patients.
