Pathophysiological and CT aspects of wallerian degeneration of the corticospinal tract in the brain stem were studied in patients with old hemispheric infarcts. There was found to be a clear relationship between (a) the location and size of the infarcts and (b) the presence or absence of wallerian degeneration. When most of the motor cortex is involved, degeneration can be seen at least as far as the mesencephalic level and sometimes down to the pontine level. Isolated capsular infarcts which spare the motor cortex are also associated with degeneration. No degeneration could be seen in patients with small infarcts.
对患有陈旧性半球梗死的患者，研究了脑干中皮质脊髓束华勒氏变性的病理生理及CT表现。发现（a）梗死灶的位置和大小与（b）华勒氏变性的有无之间存在明确关联。当大部分运动皮层受累时，至少在中脑水平可见变性，有时可至脑桥水平。未累及运动皮层的孤立性内囊梗死也与变性有关。小梗死灶患者未见变性。
