Abdominal MRI, axial images through the liver: (a) STIR sequence reveals multiple high intensity focal lesions (arrows) with indistinct borders due to perilesional edema in the liver; the lesions demonstrate peripheral enhancing rim in the T1W images after administration of IV contrast medium (arrows in (b)).

Follow-up abdominal MRI, axial images through the liver: the lesions (arrows) seen in present signs of maturity. Their margin is more distinct (STIR image in (a)), as edema has resolved, and the peripheral enhancing rim is better defined (T1W image after IV contrast administration in (b)).
