case_images: Images of brain CT scan. Brain CT scan at hospital admission showing a hypodense lesion involving the right parieto-occipital region (arrow) with a predominant cortico-subcortical edematous component, associated with local sulcal effacement and right lateral ventricle collapse (A). Additional smaller lesions with edematous components (arrows) were noted bilaterally in the frontal regions (B).

case_images: A non-contrast head CT demonstrated a hypodense lesion involving the right parieto-occipital region with a predominant cortico-subcortical edematous component, associated with local sulcal effacement and right lateral ventricle collapse (Figure 1A). Additional smaller lesions with edematous components were noted bilaterally in the frontal regions (Figure 1B).
case_images: Brain MRI scan. Two axial T1-weighted images (A and B) of brain MRI showing multiple ring-enhancing lesions (arrows). The frontal lesion has sub-centimetric diameter (B), and the lesion in the inferior and posterior right temporal region measures approximately 2 cm (A).

case_images: ART was delayed until documentation of edema reduction. An MRI of the brain with gadolinium contrast revealed multiple ring-enhancing lesions (Figure 2) with surrounding edema (Figure 3), findings that couldn't rule out the suspicion of neoplasm but were more in favor of an infectious etiology. A few days later, clinical improvement and detection of T. gondii DNA in CSF confirmed the diagnosis.
case_images: Brain MRI scan. Two FLAIR images (A and B) of brain MRI showing areas of edema (arrows) in the right temporo-occipital (A) and bilateral frontal regions (B), causing sulcal effacement and locoregional mass effect.. FLAIR: fluid-attenuated inversion recovery
