• The pathological findings in four patients with courses characterized by acute coma and respiratory insufficiency occurring in obscure circumstances are presented. Carbon monoxide intoxication was excluded. After an early partial recovery from coma, the patients remained in a persistent vegetative state, with a tetrapyramidal syndrome. Pathologic changes consisted of infarction and demyelination of periventricular white matter, with associated necrotic foci in the basal ganglia in some cases.

We propose that the prolonged hypoxia and ischemia produce a "no reflow" phenomenon causing brain edema (more pronounced in the white matter); this resulted in infarctions of white matter in the periventricular arterial end and border zones.
