case_images: FIG1
case_images: Brain MRI without contrast was negative for acute intracranial abnormalities (Figure 1).
case_images: Axial plane T2 weighted MRI without contrast from the patient's second presentation: The temporal lobe of this imaging shows an abnormal T2/FLAIR signal that was determined not to have imaging characteristics compatible with an infarct and was more consistent with encephalitis.. FLAIR: fluid-attenuated inversion recovery

case_images: FIG2
case_images: The brain MRI showed an abnormal T2/fluid-attenuated inversion recovery (FLAIR) signal involving the lateral posterior aspect of the left temporal lobe (Figure 2).
case_images: Axial plane T2 weighted MRI with and without contrast from the patient's third presentation: Seen now in the temporal lobe is an irregular peripherally enhancing mass, measuring approximately 3.4 x 4.4 x 4.1cm, seemingly nodular and ill-defined in some areas with extensive surrounding edema. Also seen is a second peripherally enhancing mass centered in the left basal ganglia/caudate head, measuring approximately 2.9 x 2.7 x 2.6 cm. There is approximately 11 mm of left-to-right midline shift.

case_images: The MRI showed an irregular and nodular peripherally enhancing mass, measuring approximately 3.4 x 4.4 x 4.1 cm, with extensive surrounding edema (Figure 3).
