Abstract

The most prominent MRI finding of abcess is the peripheric enhancement following gadolinium injection. This

finding usually persists despite the reduced volume of abcess and clinical improvement. In this study we presented

the succeeding diffusion weighted images of 45 years old patient with two brain abcesses representing pre and

postsurgical period. Those abcesses were in the frontal lob and measuring about three centimeters. Though the size

of the abcess decreased after surgery, the conrast enhancement was still present in the operation site. The restricted

diffusion that was noted on the presurgical images was disappeared. As the persistent contrast enhancement in the

operation site of abcess can be misleading, the diffusion weighted images should be prefered for the evaluation of

postsurgical recurrence.
