A diffusion‐weighted imaging (DWI) lesion changed dramatically in a hyperacute stroke case treated with intravenous tissue‐plasminogen activator (IV t‐PA). The initial hyperintense lesion on DWI disappeared completely immediately after IV t‐PA treatment without improvement of neurological symptoms. However, the lesion reappeared 24 hours later. Successful thrombolysis can resolve DWI lesions but does not always improve the neurological symptoms.
