[Echinococcus granulosus--diagnostics and therapy problems--case report].

The case report of patient with asymptomatic liver echinococcosis several year observing was shown. The liver cyst occasionally revealed by ultrasound examination had doubled its diameter in two years, serological test result had suggested Echinococcus granulosus infection. After the initially treatment with benzimidazole the curative surgery had been conducted and histological examination confirmed the liver echinococcosis diagnosis. The headaches in two years after surgery needed the central nervous system echinococcosis considering in differential diagnostics. Because of the normal liver parenchyma ultrasound image, normal laboratory tests results and negative serological tests results the patient was considered as completely recovered after several year of observation. On the base of procedure undertaken the diagnostics and therapeutic possibilities were reviewed. The necessity of taking the echinococcosis into account in occasionally found liver cysts differential diagnostics and individual choice of the optimal therapeutic schema was underlined.
