Background and Purpose: Traumatic head injury has a high mortality and morbidity in low- and middle-income countries. Brain injury following trauma is the cause of death in about one-third of patients that die after trauma. The aim of the study was to assess the pattern of computed tomography (CT) findings in head trauma at the tertiary health institutions serving the Niger Delta region of Nigeria. Patients and Methods: The CT scans of the head of 310 consecutive patients referred specifically for evaluation of head injury were prospectively reviewed. The images acquired were analyzed by the radiologists. The radiological features and anatomical distribution of the lesions on the CT Images were assessed and documented. Patients with congenital abnormalities of the head and those whose fall or injury were secondary to stroke were excluded from the study. The Ethical Committee of our institutions gave approval for the study. Results: There were 225 (72.58%) males and 85 (27.42%) females. About 44.84% of the patients were in the third and fourth decades of life. The major causes of head injury were road traffic accidents in 67.74%, falls in 14.84%, and assaults in 7.42%. Most of the patients 102 (33.0%) presented within the 1st week of injury. Cranial fractures were found in 87 (28.06%) patients. In this series, 111 (35.81%) had normal CT findings while 199 (64.19%) had abnormal CT findings. Intra-axial lesions were the most common, constituting 131 (42.26%) cases. Conclusion: This study had demonstrated that majority of head trauma evaluated by CT were associated with cranial and brain injuries. Intra-axial injuries are more prevalent. Poor health facilities and bad road networks in addition to being risk factors for head injury also hamper the management of head-injured patients as shown by the long duration of injury before health facilities are accessed.
