case_images: At 3 weeks from initial presentation, a MRI brain demonstrated an 11 mm peripherally enhancing intra-axial lesion along the right superior temporal gyrus with blood products and vasogenic edema [Figure 1a and b]. A repeat MRI brain 1-month later demonstrated the persisting 10 mm x 4 mm peripherally enhancing lesion with slightly decreased surrounding edema [Figure 1c and d].
