In 2003, the WHO Informal Working Group on Echinoco - ccosis (WHO-IWGE) proposed a standardised ultrasound ( Table 6.1 ). This is universally accepted, particularly because it helps to decide on the appropriate management. Three groups have been recognised: /uni25CF Group 1: Active group – cysts larger than 2 cm and often fertile. /uni25CF Group 2: Transition group – cysts starting to degenerate and entering a transitional stage because of host resistance or treatment but may contain viable protoscolices. /uni25CF Group 3: Inactive group – degenerated, partially or totally calcified cysts; unlikely to contain viable protoscolices.
