case_images: Cranial magnetic resonance imaging (MRI) with contrast. Upper panel: T1-weighted images with contrast showing the multiple vari-sized enhancing lesions (white arrows) in both cerebral hemispheres and posterior fossa. The known right frontal lobe tumor is still seen (black arrowhead). Lower panel: fluid attenuation inversion recovery (FLAIR) showing extensive perilesional edema (black arrows).

case_images: The cranial MRI revealed multiple vari-sized enhancing lesions in both cerebral hemispheres and in the posterior fossa with perilesional edema on FLAIR sequence (Fig. 1).
case_images: Brain scan using thallium-201 planar images showing no abnormal increase in tracer uptake.

case_images: SPECT scan of the brain was performed to distinguish between toxoplasmosis and tumor recurrence. SPECT images did not show increased tracer uptake in any of the lesions, a finding more consistent with cerebral toxoplasmosis (Fig. 2).
