目的:了解嗜铬细胞瘤(PCC)在缺乏儿茶酚胺(CA)测定条件下的定性诊断。方法:回顾性分析22例PCC的临床特点及24小时尿VMA测定,立其丁试验为定性诊断。结果:临床主症为高血压、头痛、心悸、多汗;24小时VMA测定、立其丁试验均阳性,阳性率达100%。22例患者全部诊断为PCC。结论:本组病例资料提示:PCC、VMA测定及立其丁试验仍可作为本病的筛选试验,且为价值较高,方便、经济的定性诊断方法。 Objective: To understand the qualitative diagnosis of pheochromocytoma (PCC) in the absence of catecholamine (CA) assay. Methods: The clinical features of 22 cases of PCC and 24-hour urinary VMA were retrospectively analyzed. The stereotypic assay was used as a statin test. Results: The main symptoms were hypertension, headache, palpitations, and hyperhidrosis; 24-hour VMA and Ricardin tests were positive, and the positive rate was 100%. All 22 patients were diagnosed with PCC. Conclusion: The data of this group of cases suggest that PCC, VMA determination and Ritutin test can still be used as a screening test for this disease, and it is a high value, convenient and economical qualitative diagnostic method.
