Overview of the EMUC-CT after Graeter et al. Left: Primary morphological types I–V and their subcriteria (applicable to types I, II and III). Right: Patterns of calcification. (EMUC-CT = Echinococcus multilocularis Ulm Classification for Computed Tomography). The two columns of the classification are primarily considered separately and can then in principal be freely combined. There are two exceptions: The pattern of calcification “with a central calcification*” can only occur with primary morphology type IV* and primary morphology type V is not further characterised by a pattern of calcification. Lesions of types I and II with cystoid portions as well as types III and IV were evaluated (marked with a green frame).
