Abstract

Of 60 patients with acute carbon monoxide (CO) intoxication caused by accidental or intentional inhalation of natural gas, smoke inhalation, or inhalation of automobile exhaust, 23 had characteristic computed tomographic findings. The most common finding, seen in 21 patients, was symmetric and diffuse low density in the cerebral white matter, which was more advanced in the centrum semiovale and varied in degree from slight to severe. In 18 patients there was a symmetric, bilateral, round low-density lesion in the globus pallidus. The size of the lesion varied from small (limited to the globus pallidus) to large (extension to the internal capsule). Of the 23 patients, six made a good recovery, four recovered with some disabilities, eight remained in a vegetative state, and five died. The prognosis depended on the severity of the cerebral white-matter changes and not on the size of the low-density lesion of the globus pallidus.

摘要

在60例因意外或故意吸入天然气、烟雾或汽车尾气导致急性一氧化碳(CO)中毒的患者中,23例有特征性的计算机断层扫描结果。最常见的表现见于21例患者,为脑白质对称性弥漫性低密度影,在半卵圆中心更为明显,程度从轻度到重度不等。18例患者苍白球有对称性、双侧圆形低密度病变。病变大小从小(局限于苍白球)到 大(延伸至内囊)不等。23例患者中,6例恢复良好,4例恢复后有一些残疾,8例处于植物人状态,5例死亡。预后取决于脑白质改变的严重程度,而非苍白球低密度病变的大小。
