Long-term follow-up of liver alveolar echinococcosis using echinococcosis multilocularis ultrasound classification

Figure 5 Hepatic alveolar echinococcosis reference lesions (arrow) in segment II/IVa/VIII (patient 1) and segment II/III (patient 2), respectively. A and C: initially classified as pseudocystic pattern (patient 1: A, patient 2: C); B and D: In the course of each case loss of the centrally echo-poor, liquid-impressive zone and increasing calcification structures, indicating a change in sonomorphology with a transition to a hailstorm pattern (patient 1: B; patient 2: D). The ultrasound images shown are from the current patient collective.
