Abstract

The perfusion change in acute symptomatic hypoglycemic encephalopathy (ASHE) is not well known. We present the perfusion-weighted imaging of a patient with ASHE. The area of diffusion-weighted imaging abnormalities and adjacent normal-appearing white matter showed increased cerebral blood volume and flow, and shortening of time-to-peak.

  Fig. 1 Diffusion-weighted imaging (DWI) (a) and apparent diffusion coefficient map (b) revealed diffusion restriction along the right corona radiata of the corticospinal tract. Relative cerebral blood volume (c) and relative cerebral blood flow (d) showed increased perfusion in the area of DWI abnormalities and adjacent normal-appearing white matter. Hyperperfusion was predominant in the DWI abnormalities and the deep white matter posterior to the DWI lesion (double arrows), and the white matter near to the cortex (arrows) showed mildly increased perfusion.
