Simultaneous diffusion-weighted magnetic resonance images and brain blood perfusion scintigraphy for a transient lesion in the splenium of the corpus callosum.
A transient lesion in the splenium of the corpus callosum is a rare disease and its pathogenesis is unclear. We performed simultaneous diffusion-weighted magnetic resonance images and brain blood perfusion scintigraphy for a transient lesion in the splenium of the corpus callosum. This transient lesion showed hyperintensity on the diffusion-weighted images and hypointensity on the apparent diffusion coefficient map. However, normal blood perfusion was observed on brain blood perfusion scintigraphy. Transient axonal or intramyelinic edema might be a cause of the transient lesion in the splenium of the corpus callosum.
