Computed tomography (CT) of the head (Figure 1) showed a left temporal lobe mass-like lesion, with surrounding vasogenic edema.
Magnetic resonance imaging of the brain shows a septated rim-enhancing mass lesion in the left temporal lobe, with bright, restricted diffusion, and diffuse surrounding vasogenic edema (arrow).

The next day, she was subjected to magnetic resonance imaging (MRI) of the brain with gadolinium contrast (Figure 2), which showed a left temporal lobe septated rim-enhancing mass lesion, with bright restricted diffusion and diffuse surrounding vasogenic edema.
Abundant neutrophils and necrotic debris.. Note: Minute fragment of brain tissue is visible in the left lower corner (hematoxylin & eosin, original magnification 20x).

Brain biopsy showed abundant acute inflammatory cells (neutrophils) and necrotic materials, consistent with abscess (Figure 3).
Two months follow-up: magnetic resonance imaging of the brain shows left-sided craniotomy changes with interval collapse of postoperative cavity and decreased surrounding edema and enhancement (arrow).
