The diagnosis in two cases of neural crest tumours was confirmed by the measurement of concentration of plasma catecholamines. A histamine provocative test monitored by values of plasma catecholamines provided support for a diagnosis of pheochromocytoma in a patient with normal blood pressure and elevated values of urinary amines. In the second case the presence of a ganglioneuroblastoma secreting abnormal amounts of catecholamines was detected by plasma epinephrine and norepinephrine measurements when values of urinary free catecholamines were normal.
通过测量血浆儿茶酚胺浓度确诊了两例神经嵴肿瘤。在一名血压正常但尿胺值升高的患者中,通过血浆儿茶酚胺值监测的组胺激发试验为嗜铬细胞瘤的诊断提供了支持。在第二例病例中,当尿游离儿茶酚胺值正常时,通过测量血浆肾上腺素和去甲肾上腺素检测到存在分泌异常量儿茶酚胺的神经母细胞瘤。
