Highlights Cerebrovascular disease as a risk factor for COVID-19 mortality. Future studies will allow the development of risk scales in patients with COD19 and a history of stroke. More clinical trials are need to explore the effect of history of stroke and COVID19.

This article conducts a contemporary comparative review of the medical literature to update and establish evidence as to which framework among Rotterdam and Marshall computed tomography (CT)-based scoring systems predicts traumatic brain injury (TBI) outcomes better. The scheme followed was following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines for literature search. The search started on August 15, 2020 and ended on December 31, 2020. The combination terms used were Medical Subject Headings terms, combination keywords, and specific words used for describing various pathologies of TBI to identify the most relevant article in each database. PICO question to guide the search strategy was: “what is the use of Marshall (I) versus Rotterdam score (C) in TBI patients (P) for mortality risk stratification (O).” The review is based on 46 references which included a full review of 14 articles for adult TBI patients and 6 articles for pediatric TBI articles comparing Rotterdam and Marshall CT scores. The review includes 8,243 patients, of which 2,365 were pediatric and 5,878 were adult TBI patients. Marshall CT classification is not ordinal, is more descriptive, has better inter-rater reliability, and poor performance in a specific group of TBI patients requiring decompressive craniectomy. Rotterdam CT classification is ordinal, has better discriminatory power, and a better description of the dynamics of intracranial changes. The two scoring systems are complimentary. A combination of clinical parameters, severity, ischemic and hemodynamic parameters, and CT scoring system could predict the prognosis of TBI patients with significant accuracy. None of the classifications has good evidence for use in pediatric patients.

Introduction: Traumatic brain injury is a major public health problem worldwide, with higher incidence rates in low- and middle-income countries. In this context, the development of major complications has been evidenced, such as the formation of haemorrhages due to traumatic rupture of a cerebral aneurysm, which may threaten the patient's life and therefore require immediate medical and neurosurgical procedures. Case: We present the case of a male patient in the fourth decade of life, who presented a closed head trauma with the consequent development of subarachnoid haemorrhage in the territory of the right middle cerebral artery secondary to traumatic aneurysmal rupture Conclusion: One of the complications that can occur in the context of head trauma is the development of subarachnoid haemorrhage due to traumatic aneurysmal rupture. Despite therapeutic options, these scenarios continue to be a challenge in low- and middle-income countries due to the lack of specialized tools in neurosurgical and neurorehabilitation areas
