We read the article entitled Stroke with persisting false-negative diffusion-weighted imagings: A case report on the esteemed Joal of Acute Disease with great interest. The author reported a case of an elderly male individual with acute onset of dysarthria and right lower paresis. Brain MRI images after 6 and 19 h were normal; only after 180 h the diffusion restriction in the medullary region was observed. This study revealed the importance of the neurological examination associated with the repetition of imaging studies when the diagnosis is unclear[1].
