    Delayed neurological deterioration after head injury can be caused by cerebral vasospasm. This rare complication may be linked to blood degradation products, detectable by CT scans.

    Area of Science:

    • Neuroscience
    • Trauma Surgery

    Background:

    • Cerebral vasospasm is common after head injury.
    • Delayed neurological deterioration secondary to vasospasm is rare.

    Observation:

    • A 57-year-old man with acute subdural hematoma and subarachnoid hemorrhage developed delayed neurological deficits (aphasia, hemiparesis) on postoperative day 10.
    • Angiography revealed vasospasm; CT scan showed persistent blood in the cisternal space.

    Findings:

    • Delayed posttraumatic vasospasm, potentially due to blood degradation products, is implicated in the patient's deterioration.
    • Computed tomography (CT) may predict vasospasm, while digital subtraction angiography can demonstrate it.

    Implications:

    • This case highlights the rare but significant role of delayed vasospasm in head injury outcomes.
