Repeat angiography in temporal contusions

S Cronqvist, U Tylén

    Acta Radiologica: Diagnosis

    Summary
    This summary is machine-generated.

    Bilateral Sylvian vessel filling aids temporal contusion diagnosis by enabling side-to-side comparison. Midline shifts may appear later, reflecting the true lesion size after trauma.

    Area of Science:

    • Neurology
    • Radiology
    • Neurosurgery

    Background:

    • Temporal contusions are traumatic brain injuries affecting the temporal lobe.
    • Accurate assessment of contusion size is crucial for patient management.
    • Early diagnosis of temporal contusions can be challenging.

    Purpose of the Study:

    • To evaluate the utility of bilateral Sylvian vessel filling in diagnosing temporal contusions.
    • To understand the temporal evolution of midline shift in relation to contusion size.

    Main Methods:

    • Utilizing angiography to visualize Sylvian vessels bilaterally.
    • Comparing Sylvian vessel displacement between the affected and contralateral sides.
    • Assessing midline structures for shifts at different time intervals post-trauma.

    Main Results:

    • Bilateral Sylvian vessel filling allows for direct comparison between cerebral hemispheres.
    • In the acute stage, significant contusions may not show a corresponding midline shift.
    • Midline shift becomes more apparent with a longer interval between trauma and angiography, indicating lesion progression.

    Conclusions:

    • Bilateral Sylvian vessel filling is a valuable technique for the early diagnosis of temporal contusions.
    • The absence of a midline shift in the acute phase does not exclude a large temporal contusion.
    • Angiography over time provides a more accurate assessment of temporal contusion severity.
