Poster Abstract
We report a case of a 42-year-old female whose diffusion-weighted magnetic resonance imaging (MRI) performed 28 hours after symptom onset was negative for acute infarction. Repeat MRI 3 days later demonstrated left-sided corona radiata infarction.
Diffusion-weighted MRI imaging may not be sensitive or specific enough in early stages of acute stroke. Caution should be used in relying on imaging alone to make the diagnosis of ischemic stroke. Clinical assessment likely should be given priority in determining appropriate initial treatment and the need for secondary stroke prevention treatment when imaging is negative. Consideration should be given to the timing of initial MRI and repeating an MRI if it is negative and clinical suspicion is high for ischemic stroke.
