MRI

• 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.
