case_images: MRI of the brain revealing a single, large, right, frontoparietal, ring-enhancing lesion with high signal intensity on T2-weighted images, low signal intensity on T1-weighted images and restricted diffusion on diffusion-weighted images.

case_images: A repeated brain MRI scan showed a worsening of the lesion, and the hypothesis of brain abscess was strongly considered (fig. 1).
case_images: MRI of the brain showing worsening of the right frontoparietal lesion after 4 weeks of treatment with ceftriaxone combined with metronidazole. On T2-weighted images, the central abscess is hyperintense, with a hypointense surrounding capsule and extensive surrounding edema.

case_images: Another brain MRI was performed, with evidence of further worsening of the lesion (fig. 2).
case_images: MRI of the brain evidencing almost complete resolution of the cerebral abscess after 12 weeks of treatment with trimethoprim-sulfamethoxazole.

case_images: There was also a favorable imaging response, with brain MRI undertaken a month after starting this therapy revealing almost complete resolution of the brain abscess (fig. 3).
