In the Department of General Surgery of Medical University 11 patients with hydatid cysts of liver were operated. Ultrasonography and computer tomography allowed to define exact localization, size and contents of the cysts, what made possible planning of operating procedure. In 2 cases nonanatomic resection of liver parenchyma was performed, in 2 ones with coexisting stornach neoplasm just excision of the frontal wall of the cyst and emptying of the interior. In all the other cases the cysts were removed with surrounding liver tissue. Late results of surgical treatment with albendazol therapy are good. Diagnosis of echinococcic desease should be precised, considering with possibility of coexisting foci in other organs.

Liver cysts taken from 9 patients, operated on in the Medical Academy Clinic in 2000, have been examined. Cyst layers, their thickness and content have been analysed. We have searched for the cestoid scolexes and rostellar hooks. In 6 patients Echinococcus granulosus larvae have been found. In 4 cases there have been protoscolexes discovered, however with some signs of degeneration of the larva. In one case dead larva has been diagnosed on the basis of the presence of single hooks and in one patient one larva alive with unchanged structures has been revealed. Profound parasitological examination is a good supplement to the examination of the histopathological slides, especially in the case of degenerating larvae, when the tissues of the parasite lose their contact with the connective tissue layer of the host. Separated layer fragments, as well as protoscolexes and rostellar hooks need not be exposed to histological cutting.
Cystic and alveolar echinococcosis, parasitic diseases, caused in humans by the larval stage of tapeworm Echinococcus granulosus and E. multilocularis are rare diseases in Poland. We have diagnosed 71 patients with cystic echinococcosis and 10 patients with alveolar echinococcosis during last 12 years. Echinococcosis still create significant diagnostic difficulties, particularly alveolar one. Progress and actually available radiological imaging techniques, which can be applied in the cystic and alveolar echinococcosis diagnostics, are presented. Ultrasound appearance, CT, MRI images are described. Own experience with Proton Magnetic Resonans Spectroscopy in two patients with recurrent alveolar echinococcosis are presented.
The aim of the investigation was the comparison of the diagnostic value of the clinical, radiological and ultrasonographic examinations in the diagnosis of focal changes in the liver and the determination of the relations between the changes in the ultrasound image of the liver and the changes in other organs. The investigation was performed on 24 animals: 20 dogs and 4 cats of different breeds and sex, aged 1.5 to 14 years. The ultrasonographic examinations were done using the apparatus of Bruel and Kjaer type 1849 and Concept 2000 of Dynamic Imiging. The following changes were diagnosed in the ultrasonic picture: aechogenic changes in 5 animals, hypoechogenic in 2 animals, normechogenic in 2 animals, hyperechogenic in 8 animals and changes of mixed echogenicity in 5 animals. The connection between clinical signs and the results of X-ray and ultrasonographic examination allowed the recognition of the changes in the liver as cysts, abscess and neoplasm of the liver.
