Figure 7

Cyst stages are different phases of the “natural history” of an echinococcal cyst. The upper row depicts the progressive involution (L to R) of the cyst whose cavity is gradually filled by pseudocaseous inflammatory material. Dotted lines indicate relapses from previously transitional and inactive stages, with the growth of new daughter cysts.
