Hemorrhage in the Wall of Pyogenic Brain Abscess on Susceptibility Weighted MR Sequence: A Report of 3 Cases
Figure 3
(a) Post gadolinium T1 SE image shows the ring enhancing wall of the abscess (arrow). (b) Susceptibility weighted image shows prominent hypointensity (arrow) in the wall from presence of hemorrhage. (c) Diffusion image demonstrates bright signals due to restricted diffusion from the pus in the center of the abscess. (d) Apparent diffusion coefficient (ADC) map shows corresponding dark signals confirming true restricted diffusion in the center of the abscess.
