The purpose of the present study was to clarify the clinical features of acute multiple brain infarction using diffusion-weighed MR imaging (DWI). We investigated 39 consecutive patients with supratentorial ischemic stroke showing recent multiple brain lesions on DWI performed within 7 days of stroke onset. The patients were classified into two groups according to the distribution of lesions on DWI : patients with small scattered lesions (group A), and those having a large cortical lesion with other scattered ones (group B). We compared the clinical characteristics, clinical course and outcome between the two groups. The patients in group A presented with a history of TIA within 7 days prior to the index episode, mild neurologic deficits on admission, fluctuations in neurologic deficits, and a good outcome was more frequently observed than in the group B patients. Severe stenosis of the major cerebral arteries was also encountered more frequently in the group A patients, and was inferred to be a potential contributing factor to small, multiple, scattered brain infarcts.
