Table 2

International classification of ultrasound images in cystic echinococcosis for application in clinical and field epidemiological settings.

Tybe of Cyst	Status	Ultrasound features	Remarks
CL	Active	Signs no pathognomonic, unilocular, and no cyst wall	Usually early stage, not fertile, and differential diagnosis necessary
CE 1	Active	Cyst wall, hydatid sand	Usually fertile
CE 2	Active	Multivesicular, c st wall, and “rosette-like”	Usually fertile
CE 3	Transitional	Detachment of laminated membrane, “water-lil sign,” less round-decreased intracystic pressure	Starting to degenerate, may produce daughter cysts
CE 4	Inactive	Heterogeneous hypo- or hyperechogenic degenerative contents, no daughter cysts	Usually no living protoscoleces, differential diagnosis necessary
CE 5	Inactive	Thick calcified wall, calcification partial to complete, and not pathognomonic but highly suggestive of diagnosis	Usually no living protoscoleces
