| Abstract: | Seven cases of ischaemic accident affecting the brain stem are reported. There were two lacunar infarctions and five infarctions due to occlusion of major arteries (two lateral medullary infarctions, one pontine infarction and two thalamo-mesencephalic infarctions). In every case the abnormalities detected at MRI were concordant with the clinical findings. The authors underline the value of MRI in establishing clinico-topographic correlations in vivo and in differentiating lacunar infarctions from infarctions due to stenosis of major arteries in the vertebro-basilar system. |
