ABSTRACT
In the 1970s, J. H. Adams and other researchers at the Institute of Neurological Sciences, Glasgow, Scotland introduced a grading system for the quantification and analysis of contusions of the brain. They derived a brain contusion index based on regional surface distribution and parenchymal depth of contusions of the brain. Following a subsequent modification of this scheme in the 1980s, they recommended evolving modifications that will fit a variety of possible applications. Having tested the applicability of this grading system for the forensic/medico-legal autopsy, we have encountered some applied anatomic limitations and have derived a modification that addresses these limitations in reference to the forensic/medico-legal autopsy.We recommend a two-tier system based on the Adams' system, which quantifies contusions of the brain by the gyral spread of contusions and by the parenchymal depth of penetration of contusions with a re-definition of the lobar distinctions and classifications of the brain. Gyral spread is assigned a grading scheme of 0-3 and the parenchymal depth of contusions is assigned a grading scheme of 0-4. A lobar contusion score is derived by multiplying the two assigned grades. A total brain contusion index is derived by summating all the lobar contusion scores. This reproducible grading system can be applied to routine bench forensic neuropathology reporting, court room illustrations and in comparative research analysis of brain trauma subjects.
