Overview

Pretreatment amebic liver abscess appears as a heterogeneously low-signal intensity mass with sharp borders on T1 and as a hyperintense region with hyperintensity extending to the liver surface, corresponding to edematous hepatic parenchyma.
Progression of edema is followed with T2-weighted imaging.
Posttreatment amebic liver abscess becomes homogeneously hypointense on T1-weighted images.
Maturation of the abscess wall during and after treatment is characterized by the appearance of concentric rings.
Differential for MR findings for amebic liver abscess also includes bacterial abscess, hematoma and necrotic tumor.
