CT, MRI and DWI Features of a Solid Organizing Hepatic Abscess
Figure 2
MRI of the liver. (a) The nodular mass is hypointense on axial GE T1-weighted out-of-phase MRI. (b) The lesion exhibits a target-like appearance on coronal T2-weighted HASTE MRI, the rim being higher in signal intensity than the central component. The tine colliquative core is clearly visible. (c) The central component is hyperintense on DWIb400, while the rim is not appreciable; the colliquative nucleus and the cerebrospinal fluid are hyperintense because of T2-shine-through effect. (d) ADC map shows no water diffusion restriction of the rim and the core. (e) and (f) Contrast-enhanced pattern of the nodule on dynamic MRI (arterial and late venous phases) is similar to the pattern of dynamic CT.
