Brain contusions: the time sequence of the histological changes.

E M Løberg, A Torvik

    Medicine, Science, and the Law
    |April 1, 1989
    PubMed
    Summary

    Histological examination of brain contusions can accurately determine lesion age. Microscopic changes appear within an hour and evolve predictably over time, aiding forensic analysis.

    Area of Science:

    • Neuropathology
    • Forensic Science

    Background:

    • Brain contusions are common traumatic brain injuries.
    • Accurate dating of contusions is crucial for legal and medical investigations.

    Purpose of the Study:

    • To establish histological criteria for determining the age of brain contusions.
    • To correlate microscopic findings with the known age of lesions.

    Main Methods:

    • Microscopic examination of brain contusion sections from 65 cases.
    • Analysis of histological alterations at different time points post-injury.

    Main Results:

    • Earliest histological changes observed within one hour of lesion.
    • Progressive and orderly changes in lesion morphology over hours, days, and weeks.
    • Histological features allow for age estimation of brain contusions.

    Conclusions:

    • Routinely stained histological sections provide reliable data for age determination of brain contusions.
    • Histological analysis is a valuable tool in forensic neuropathology.
