Possible Occurrence of Delayed Leukoencephalopathy Following Acute Ischemic Stroke With Large-Vessel Occlusion.

ABSTRACT:

Background

Typically detected at least 14 days after acute ischemic stroke onset, delayed leukoencephalopathy (DL) involves diffuse hyperintensities restricted to white matter on fluid-attenuated inversion recovery accompanied mostly by partial diffusion-weighted image hyperintensities. DL cases, which are rarely reported, have occurred after large-vessel occlusion (LVO). Herein, we aim to elucidate the incidence and factors associated with DL.

Methods

Our study covers consecutive ischemic strokes involving: (1) onset-to-door time within 7 days and (2) available scans from at least a second magnetic resonance imaging procedure at least 14 days after onset. First, we examined the incidence of DL generally and whether LVO could be a risk factor for DL in ischemic strokes gener
