Abstract
|
|
|
|
The reversible splenial lesion syndrome is a clinicoradiological syndrome presenting with the presence of transient lesions restricted to the splenium of the corpus callosum associated with encephalitis or encephalopathy of varied etiology. A lesion involving the splenium of the corpus callosum has been rarely reported in hypoglycemic encephalopathy. A 62-year-old man presented with mental deterioration associated with hypoglycemia. Diffusion-weighted MR imaging showed increased intensity lesion in the splenium of the corpus callosum with decreased apparent diffusion coefficient in the same area. After glucose infusion, the patient showed dramatic rec overy of disturbed consciousness. After 2 days, follow-up brain MR imaging revealed complete resolution of the splenial lesion.
