The morbidity and mortality from neurological conditions is constantly increasing around the world. They are responsible for 6.8 million deaths per year and represent the leading cause of non-traumatic acquired disability in adults. Objective: The aim of this study was to evaluate the interest of CT in the diagnosis of cerebrovascular and traumatic pathologies encountered at the CHU-RN of Ndjamena-Chad. Materials and methods: We conducted a cross-sectional and retrospective study over a period of 06 months from July to December 2024 on cerebrovascular or traumatic pathologies in CT. Our study was based on a questionnaire submitted to patients designed using Word software. The data was collected by Microsoft Excel 2016 software and then analyzed using SphinxV5 and XLStat7.5 software. Results: We recorded 150 patients with a male predominance of 68.7% against 31.3% of women, i.e. a sex ratio (M/F) of 2.19. The average age was 38 ± 20.48% with extremes of 12 and 102 years. The profession was largely represented by pupils/students, i.e. 50.77%; 48% of patients were married and all lived in urban areas. Coma was the predominant physical sign, 28%, while hypertension was the predominant risk factor, 35.33%. The majority of examinations were performed between 5 and 10 days after the onset of symptoms. The most common indication was TCE, i.e. 58.67%. The majority of the results were pathological, i.e. 70% with 23.81% of hemorrhagic strokes located in the fronto-parietal area (28.57%). The CT aspects of DALYs were hypodensity unlike AVCH and brain tumors which were hyperdensity. The CT appearance of the extradural hematoma was that of spontaneous biconvex lens hyperdensity; the chronic subdural hematoma appeared in the form of a lunar crescent hypodensity, on the other hand, the meningeal hematoma and the intracranial hematoma appeared respectively in the form of an iso-density and a well-limited hyperdensity. Conclusion: CT remains the first-line examination in the diagnosis of cerebrovascular and traumatic pathologies. Making it easy to access, the populations will help improve their care.
