A consecutive series of ten patients with chronic bronchitis and hypercapnia were studied. All seven patients with chronic hypercapnia and one patient with intermittent hypercapnia showed evidence on skull radiographs of raised intracranial pressure. In five male and three female chronic bronchitics matched for age and ventilatory impairment, but without hypercapnia, no such radiological abnormalities were shown. The clinical significance and pathophysiology of this hitherto unreported finding is discussed. It would appear that in some cases the chronicity of hypercapnia may be diagnosed from a radiograph of the pituitary fossa.
对连续的10例慢性支气管炎合并高碳酸血症患者进行了研究。所有7例慢性高碳酸血症患者和1例间歇性高碳酸血症患者的颅骨X线片均显示有颅内压升高的迹象。在年龄和通气功能损害相匹配但无高碳酸血症的5例男性和3例女性慢性支气管炎患者中，未显示出此类放射学异常。讨论了这一此前未报告的发现的临床意义和病理生理学。似乎在某些情况下，可通过蝶鞍X线片诊断高碳酸血症的慢性程度。
