摘要

Cerebral trauma is an important cause of mortality and morbidity in the elderly population. Head injury can result in both acute and long-term issues, some of which may be difficult to identify just based on the clinical findings. Early diagnosis, appropriate imaging, and prompt interventions are important to prevent any permanent complications. Early unenhanced computed tomography is key to identify any areas of bleed or edema, while magnetic resonance imaging should be reserved for complex cases and for long-term assessment. Advanced imaging techniques and functional imaging are useful adjunct tools in assessing persistently symptomatic patients. Cerebral trauma can result in a number of hemorrhagic or nonhemorrhagic primary lesions, many of which have a characteristic pattern on imaging. Secondary injuries need to be identified early as they can significantly affect the long-term prognosis and recovery. Although imaging is essential for diagnosis, one needs to be aware of the various imaging pitfalls to avoid any misdiagnosis or incorrect management.
