MRI of a 19 year-old SLE patient who presented with stupor. T2-weighted image (A) and Diffusion-weighted image (B) show normal. After 2 weeks repeat MRI, T2-weighted image (C) shows high signal lesions in bilaterally temporooccipital white matter. DWI (D) shows lesion isointensity. Follow-up T2-weighted image (C) obtained 2 week after (E) reveals almost resolution of high signal area in bilaterally lesion region. DWI (F) reveals lesion isointensity.
