Initial MRI and electroencephalogram (EEG) findings: (A) axial fluid-attenuated inversion recovery MRI of the brain showing: (A) a 7 mm x 5 mm lesion in the left frontal region (black arrowhead) and a 9 mm x 6 mm lesion in the anterior left temporal region (black arrowhead); (B) post-contrast axial T1-weighted MRI showing lesion enhancement of both lesions; and (C) the EEG was notable for left temporal slowing with some sharp features (outlined area).

Her brain MRI with contrast was notable for 2 enhancing lesions in the left frontal and temporal lobes (Fig. 1A, B). Her electroencephalogram (EEG) was notable for left temporal slowing with some sharp features (Fig. 1C).
Repeat imaging 1 month post-event showing: (A) head CT scan with a small region of encephalomalacia (white arrowheads) in the left frontal lobe; (B) axial fluid-attenuated inversion recovery brain MRI of the same lesions in the left frontal and temporal regions; and (C) the same lesions unenhanced on post-contrast axial T1-weighted MRI.

Her head CT was notable for a small region of encephalomalacia in the left frontal region (Fig. 2A). No enhancement was seen on axial T1-weighted MRI following contrast administration (Fig. 2B, C).
