Objective . Assess the role of CT in patients with hepatic echinococcosis, and compare them with morphological changes. Materials and methods . The study based on the results of examination and treatment of 18 patients with liver echinococcosis. All patients were performed CT examination on Neusoft 64 in the machine. Liver parenchymal density parameters evaluated in Hounsfield units in step of 1,5 to 5 mm, and the area determined by the liver cysts. Results of the study . Mean cyst size (length, width, thickness) were 80,5 ± 6,7 (length), 64,4 ± 4,7 (width), 57,2 ± 3,6 (thickness) mm, respectively. The average liver area 20666,7±345,0, cyst area 20666,7 ± 345,0. The density of cysts on Hounsfield was -17,4± 4,7. Density of 0,5 cm from the liver tissue cysts 24,2 ± 5,7, liver tissue density of 1 cm from the cysts 24,9 ± 5,9, Liver tissue density of cysts 1,5 cm 45,6 ± 5,5, the density of the liver 2 cm from the tissue cysts 50,2 ± 6,1., the liver tissue density of 2,5 cm from the cysts 59,2 ± 7,1, the liver tissue density of 3 cm from the cysts 71,6 ± 8,2, a density of 4 cm from the liver tissue cysts 72,2 ± 8,4, the average density of the liver tissue to remove cysts from 5 cm to 8 cm 71,4 ± 8,2. When comparing the results of computer tomography (density tissue Hounsfield) were found that the changes in the liver tissue density from 24,2 ± 5,7 to 50,2 ± 6,1 HU observed at different distances expressed morphological changes of hydatid cysts: fi-brotic changes in the liver tissue, the presence of necrobiotic changes, inflammatory infiltration, degeneration of hepatocytes and hearths hemosiderosis 2-3 degrees. In this normal liver morphology data structure of the liver was areas where parameters of liver tissue density on CT matched normal parameters. Conclusions . CT examination is highly informative in identifying liver disease and the presence of cyst volume of morphological changes in the liver.
