The invention relates to medicine, namely to pathomorphology, and it is associated with post-mortem pathomorphologic brain examination in cases of encephalopathy. The aim of the invention is to develop brain tissue post-mortem detection techniques for pathomorphologic brain examination in cases of encephalopathy, which would allow eliminating discrepancies and errors in post-mortem diagnosis of the disease. The goal is achieved by ensuring that during the pathomorphologic examination of post-mortem brain, it is removed from the skull, and the examination determines skull vaults largest span along the mid-line of the skulls inner surface CD, determines skull vaults largest span along the mid-line of the skulls outer surface GH, cuts a straight front-parietal line (starting from the frontal lobe) of the underside of the two hemispheres, exposing the brains lateral and third ventricle, then placing it in the preparation bath, fixating both sides of the hemispheres and determining the outer distance between the brains frontal horns AB, the distance along the midline EF of the lateral ventricle, and the ratio of the coefficient, thus determining post-mortem signs of encephalopathy.Linvention concerne le domaine de la médecine, à savoir la pathomorphologie, et est associée à un examen cérébral pathomorphologique post-mortem en cas dencéphalopathie. La présente invention vise à développer des techniques de détection post-mortem de tissu cérébral pour lexamen cérébral pathomorphologique en cas dencéphalopathie, qui permettraient lélimination de divergences et derreurs dans un diagnostic post-mortem de la maladie. Lobjectif est atteint en sassurant que, pendant lexamen pathomorphologique de cerveau post-mortem, il est retiré du crâne, et lexamen consiste à déterminer la plus grande envergure de la voûte crânienne le long de la ligne médiane de la surface intérieure CD du crâne, à déterminer la plus grande envergure de la voûte crânienne le long de la ligne médiane de la surf
