Proposal of an ultrasonographic classification for hepatic alveolar echinococcosis: Echinococcosis multilocularis Ulm classification-ultrasound

Figure 3 Hemangioma-like: These lesions are difficult to distinguish from atypical (e. g., partially thrombosed) hemangiomas, and often represent a significant diagnostic challenge. Sonomorphologically, the lesions present as a relatively clearly demarcated non-homogeneous tumor that appears hyperechoic in comparison with the surrounding hepatic parenchyma. Echogenicity ranges from slightly and non-homogeneously hyperechoic to strongly and homogeneous hyperechoic.
