Introduction. In some cases of multicystic forms of liver echinococcal disease, the advanced method for treatment of cystic echinococcosis faces great problems relating to the final outcome of the treatment. Case report. In May 2005, a computerized tomography of the abdomen obtained in a 27-year -old famale patient with abdominal pain revealed more than 20 echinococcal cysts measuring up to 6.7 cm in both lobes of the liver. Laboratory analyses found the value of eosinophils 6.8%, gamma globulins 29.9%, immunoglobulin E 29 600 IU/mL and the indirect hemagglutination for echinococcosis 1 : 8 196. The treatment started in December that year with the continuous administration of a daily dose of 800 mg (14.5 mg/kg body weight) of albendazole, but it was terminated two months later due to high serum transaminases values. By the end of 2006, the largest cyst detected in the left lobe of the liver had a diameter of 5.7 cm and the one in the right lobe of the liver measured 4.1 cm. There were lesions of germinative membrane found on both cysts. Six months later, praziquantel at daily dose of 2 500 mg (45.3 mg/kg body waight) was introduced into the therapy, but the treatment was terminated after eight days because of the development of exanthema. The computerized tomography of the abdomen obtained in February 2008 revealed the presence of a large number of echinococcal cysts in the liver. The largest among those cysts measured 3.5 cm while calcifications of the cyst walls were observed on some of them. None of the remaining therapeutic options for further treatmetnt of echinococcal disease could be applied. Conclusion. The presented case confirms medical therapy as the only option for the treatment of some forms of cystic echinococcosis. Benzimidazole carbamates (albendazole, mebendazole) and praziquantel are only efficacious antihelminitics currently available, and when they have to be withdrawn due to serious adverse offects, futher treatment of a patient with liver multicystic echinococcosis is impossible. Because of that there is a need to search for new and more efficient drugs for the treatment of ehinococcal disease.
