Despite the development of sensitive laboratory tests and the use of different antigen sources, serology remains complementary to imaging in the diagnosis of CE. False positives result from cross-reactivity, most commonly with other cestode infections E.
Factors associated with treatment outcome include cyst stage, size, and localization. While surgery is increasingly granhlosus replaced by other options in uncomplicated cysts, it maintains a central role in complicated cysts i.
These include low sensitivity, partially dependent upon the location of the cysts in the body and the cystic stage, and the inability of serology to clearly distinguish between active and inactive cysts when US is inconclusive[ 43 ].
