Microscopic Examination: Brain
Microscopic examination of multiple representative brain sections showed extensive tissue disruption with associated hemorrhage, with no significant abnormalities beyond those directly attributable to the recent trauma.
Microscopic Examination: Heart
Heart sections showed a moderate amount of sub-epicardial fat, with the coronary arteries, myocardial fibers, and endocardium all unremarkable.
Microscopic Examination: Lungs
Lung sections through the right upper lobe contusion exhibited disruption of alveolar walls and recent intra-alveolar hemorrhage; other sections were essentially unremarkable.
Microscopic Examination: Liver
Liver sections showed well-preserved normal hepatic architecture, with parenchymal cells displaying markedly granular cytoplasm indicating high glycogen content—the characteristic “liver biopsy pattern” of sudden death.
Microscopic Examination: Spleen
Spleen sections showed no significant abnormalities.
Microscopic Examination: Kidneys
Kidney sections showed no significant abnormalities apart from dilatation and engorgement of blood vessels of all calibers.
Microscopic Examination: Skin Wounds
Microscopic sections of skin wounds in the occipital and upper right posterior thoracic regions were essentially similar, showing loss of epidermal continuity with coagulation necrosis at wound margins; the scalp wound additionally contained several small bone fragments in the subcutaneous tissue at its margins.
