Hemorrhage in the Wall of Pyogenic Brain Abscess on Susceptibility Weighted MR Sequence: A Report of 3 Cases

Figure 1

(a) Postgadolinium axial T1 SE image shows the ring enhancing wall of the left temporal abscess (arrow). Note the lack of smooth ring enhancement. (b) Susceptibility weighted image shows prominent hypointense signals (arrow) in the lesion. (c) Diffusion image demonstrates bright signals due to restricted diffusion from the pus in the center of the abscess (arrow). (d) Apparent diffusion coefficient (ADC) map shows corresponding dark signals confirming true restricted diffusion (arrow).
