Innovation in hepatic alveolar echinococcosis imaging. "Figure 11 of paper:" Alveolar echinococcosis in a 45-year-old patient with hepatic alveolar echinococcosis (HAE). *"(a)" T2-weighted MR images showed a heterogeneous mass: note the multiple vesicles in the lesion, which showed a well-defined border on enhanced T1WI due to the absence of enhancement of the lesion itself "(b)". *"(c)" Diffusion-weighted MR images revealed a half circular hyper-intensity area at the lesion’s border with the normal liver parenchyma, which was confirmed to be metabolically active by PET "(d)" and PET/CT "(e)". *"(f)" HAE peripheral area was composed of severe fibrosis combined with a large number of inflammatory cells on the histopathological sections (Masson staining; ×100).
