The analysis of autopsy material of 2 stillborn and 22 newborns, divided into three groups was carried out. Group I consisted of the bodies of the dead due to NFH, group II - the bodies of newborns who died with the presence of general edema syndrome in the absence of NFH, group III (control) - the bodies of deceased newborns in the absence of NFH and general edema syndrome. Before autopsy, MRI was performed. On T1- and T2-weighted images was determined by the thickness and signal intensity of the skin with subcuta-neous tissue and the subsequent calculation of the tissue hydration index. The volume of fluid in the pericardial cavity, pleural and abdominal cavities determined when using three-dimensional processing of the obtained tomograms and calculated their specific volume in the corresponding cavities. Results. The values of the specific volume of free fluid in the pleural cavities and abdominal cavity less than 8% should be considered a natural postmortem sign, rather than the life-time accumulation of transudate, when examining the bodies of deceased newborns on the first day after death. The mean values of absolute and specific volumes of pleural fluid had the maxi-mum values in the NFH observations, exceeding the values of the control group by 6.3 and 5.1 times, respectively. The highest values of the absolute amount of ascites were observed in the group with general edema syndrome. In the NFH group, all cases had hydrothorax, 85.7% of cases had ascites, and 42.9% had hydropericardium. In the group of newborns with general ede-ma syndrome, hydrothorax was detected in 57.1%, ascites - in 85.7%, and hydropericardium - in 42.9% of cases. The thickness of the skin with subcutaneous tissue depended on the localization and group of research. The most pronounced deviations from the control level were recorded for the average values of the skin thickness of the anterior chest wall in group I and the scalp of the fronto-parietal region in group II. The mean values of the tissue hydration index were higher in the group with NFH, and the lowest in the control group. Conclusion. Postmortem MRI performing, allows an objective assessment of the nature and severity of anasarca and pathological fluid accumulations in the serous cavities of dead fe-tuses and newborns. In this regard, postmortem MRI is recommended as a mandatory component of the autopsy of the bodies of fetuses and newborns that died as a result of nonimmune fetal hydrops.

Ascites and hydrothorax may be the symptoms of congestive heart failure and do not always reflects presense of the decompensated liver cirrhosis. Clinical examination of patient with chronic hepatitis C which cyanosis of the lips, cervival veins pulsation, a triple heart rhythm indicated on pathology of the heart (constrictive pericarditis), which was confirmed by instrumental methods. Congestive heart failure has lead to the congestive liver in a young female patient. Regression of all the symptoms of heart failure occurred after surgical treatment (pericardectomy).
