[New imaging diagnostics of liver echinococcosis].

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.
