A Reversible Cytotoxic Lesion of the Corpus Callosum Developing after a Rapid Alteration in Cerebrospinal Fluid Pressure/Volume in a Patient with New Daily Persistent Headache

Figure 1

(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.
