C virus were all negative and blood levels of tumor markers including alpha-fetoprotein, carcinoembryonic antigen, and carbohydrate antigen 19-9 were within normal limits. Computed tomography (Fig. 1A, coronal view) and magnetic resonance imaging (Fig. 1B, axial view) of the liver revealed an approximately 9 cm-sized non-enhancing exophytic cyst with several daughter cysts, a radiologic finding typical of cystic echinococcosis of the liver, on the left lobe lateral segment of the liver.
(A) Surgically resected mass showed a 9.5 x 9.5 x 8.5 cm-sized yellowish unilocular cyst containing variable-sized several cysts. (B) Microscopically, a brood of capsules containing degenerated protoscolices of Echinococcus granulosus (arrows) were scattered on the laminated cystic walls (H&E, x200).

Grossly, the mass showed a 9.5 x 9.5 x 8.5 cm-sized yellowish unilocular cyst containing several variable-sized cysts (Fig. 2A). Microscopically, a brood of capsules containing degenerated protoscolices of Echinococcus granulosus (arrows) were scattered on the laminated cystic walls (Fig. 2B).
