Brain function is permanently or temporarily impaired and the damage of the structure could or could not be revealable with recent technology. Objectives: To assess post-traumatic CT scan brain changes to patients with mild head injuries in correlation to clinical sequelae. Patients and Methods: This prospective cohort study was conducted at Neurosurgery Department, Zagazig University Hospitals, on 75 patients of mild traumatic brain injury (mTBI) presented to emergency department at Zagazig university hospital with mean age of 26.7 years, during the period from April 2018 to September 2018. Results: The most common CT finding in patients with mild head injury in our study was a skull fracture by 43% then contusion by32% and Epidural hemorrhage by 21.5% and least one was Subarachnoid hemorrhage by10.7% none of the participants in our current study had a subdural hemorrhage. percent of positive findings on CT scan was 9.3% and 2.6% need surgical intervention , the outcome of the patient was assessed by Glasgow outcome score (GOS) and most of the patient score was 5 which a good score. Conclusion: Patients with mild traumatic head injury with a presenting GCS score of 13 or 14 should undergo a CT scan examination and to be admitted for observation and management.
