    Summary

    Computed tomography (CT) effectively detects a range of traumatic brain injuries, from acute bleeding to chronic changes. Follow-up CT scans reveal delayed complications, enabling timely surgical intervention to prevent permanent damage.

    Area of Science:

    • Neurology
    • Radiology
    • Trauma Surgery

    Background:

    • Computed tomography (CT) is crucial for diagnosing traumatic brain injuries.
    • Traumatic abnormalities present diverse findings on CT scans, requiring careful interpretation.

    Purpose of the Study:

    • To outline the spectrum of traumatic abnormalities detectable by CT.
    • To highlight the role of CT in identifying acute and late traumatic brain changes.
    • To emphasize the utility of follow-up CT in managing traumatic brain injury.

    Main Methods:

    • Review of CT findings in patients with traumatic brain injuries.
    • Analysis of acute traumatic abnormalities including edema, contusion, and hematomas.
    • Evaluation of late traumatic changes such as hygromas, infarcts, and hydrocephalus.

    Main Results:

    • CT demonstrates a wide array of acute traumatic lesions: cerebral edema, contusion, intracerebral/extracerebral hematomas, subarachnoid/intraventricular hemorrhage.
    • Late CT findings include chronic subdural hygroma, post-traumatic infarct, porencephaly, and hydrocephalus, which can mimic degenerative or ischemic diseases.
    • Follow-up CT scans are essential for monitoring lesion evolution and detecting occult, treatable delayed sequelae.

    Conclusions:

    • CT is indispensable for the comprehensive evaluation of traumatic brain injuries.
    • Distinguishing late traumatic changes from other brain pathologies requires careful consideration of clinical history and serial imaging.
    • Serial CT scanning aids in optimizing patient management and preventing irreversible neurological deficits.
