ABSTRACT

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.
