case_images: (a-c) MRI brain completed 16 days after lumbar puncture demonstrating an oval-shaped focus of abnormal unenhancing T2/FLAIR hyperintensity with restricted diffusion of the splenium of the corpus callosum (arrow). (a) Axial diffusion. (b) ADC mapping confirms true restricted diffusion. (c) Axial T2. (d, e) MRI brain completed 14 days after initial MRI with near-to-complete resolution of the corpus callosum lesion (arrow). (d) Axial diffusion. (e) Axial T2.

case_images: LP to look for any secondary causes for her worsening head pressure, and this demonstrated a cytotoxic edematous lesion in the splenium of the corpus callosum (Figures 1(a)-1(c)). Laboratory studies (CBC and basic metabolic panel) were normal at the time of neuroimaging. Repeat imaging 2 weeks later noted near-to-complete resolution of the lesion (Figures 1(d) and 1(e)).
