Spontaneous cerebral abscess due to Bacillus subtilis in an immunocompetent male patient: A case report and review of literature

Figure 1 Pre-operative brain magnetic resonance imaging scan with intravenous Gadolinium administration. A: Axial diffusion-weighted imaging (DWI) image shows high signal of the lesion in right upper parietal lobe (black arrow); B: Axial DWI ADC map reveals low signal at the same area, due to restricted diffusion (white arrow); C: Axial post-Gd image, shows rim enhancement of the lesion (white arrowhead) as well as enhancement of the adjacent dura (white arrow).

Figure 2 Follow-up brain magnetic resonance imaging scan with intravenous Gadolinium administration, at two months post operation. A: diffusion-weighted imaging shows complete removal of the lesion, with normal diffusion of the brain parenchyma; B: Axial post-Gd image, shows minimal enhancement of the adjacent dura, due to the previous surgery (white arrow).
