Traumatic Brain Injury presents a global health concern, as it has become one of the leading causes of death and disability worldwide. Non-contrast head computed tomography (CT) scans have been used widely as a diagnostic tool in acute head injury because they are cost-effective, widely available, and detect haemorrhages with high sensitivity. We aimed to study the prevalence of intra and extra axial haemorrhages in patients presenting with head injury in and around Kanchipuram district of Tamil Nadu and also to further identify the commoner types of intracranial haemorrhages associated with such injuries. A retrospective observational study was conducted in the Department Of Radiology, Saveetha Medical College and Hospital for a period of 6 months. Image data from CT scans of the brain were obtained for 50 patients presenting with skull trauma and clinical suspicion of intracranial haemorrhage during the time period from January 2020 to May 2020 and were studied. Based on our study, out of the 50 subjects included it was observed that in the setting of traumatic head injury extra axial hemorrhages are more common than intra axial hemorrhages. Among the type of extra axial hemorrhage , extra dural hemorrhage was far more common than subdural and sub arachnoid hemorrhage especially in presence of skull fractures.
