儿茶酚胺增多症(附95例报告)

目的 提高儿茶酚胺增多症的诊断和治疗水平。方法 报告95例儿茶酚胺增多症的临床资料，其中嗜铬细胞瘤74例，肾上腺髓质增生2l冽。嗜铬细胞瘤组有高血压67例(90．5％)，24h尿VMA增高者62例(83．8％)，尿儿茶酚胺增高者67例(90．5％)；影像学检查均有阳性发现。肾上腺髓质增生患者均有高血压，24h尿VMA均增高，大部分(15／16)患者尿儿茶酚胺高于正常；21例中14例B超有阳性发现。结果 74例嗜铬细胞瘤患者均行手术治疗，其中异位嗜铬细胞瘤9例；病理及随访证实5例为恶性嗜铬细胞瘤。21例肾上腺髓质增生者中，18例行手术治疗，其中12例单侧肾上腺切除，6例双侧肾上腺切除，术后病理诊断肾上腺髓质增生。结论 嗜铬细胞瘤的诊断重点在定性诊断，而儿茶酚胺症的诊断难点在定位诊断。肾上腺髓质增生作为独立疾病概念的建立，丰富和完善了儿茶酚胺增多症的理论。

Hypercatecholaminism(report of 95 cases)

Objective To evaluate the improvement of diagnosis and treatment of hypercatecholaminism. Methods A total of 95 cases of hypercatecholaminism were reviewed.Of them 74 cases were of pheochromocytoma and 21 cases were of adrenal medullary hyperplasia (AMH).In pheochromocytoma group,67 cases (90.5%) had symptom of hypertension.Increase in 24 h urinary VMA occurred in 62 cases (83.8%) and elevated urinary catecholamine level in 67(90.5%).All thses had positive findings of ultrasound,CT scan and MRI.In AMH group,all the patients were hypertensive and their 24 h urinary VMA was increased.Most of them (15/16) had higher urinary catecholamine level than normal;14 out of the 21 cases had positive findings of B-ultrasound examination. Results Surgical operations were performed in the 74 patients with pheochromocytoma including 9 cases of extra-drenal pheochromocytoma.Of them 5 cases were confirmed as malignant pheochromocytoma.In the 21 cases of AMH,18 undewent surgical operation.Of them 12 received unilateral resection and 6 received bilateral resection of adrenal gland.The pathological examination confirmed the diagnosis of AMH. Conclusions The diagnosis of pheochromocytoma should be focused on endocrinological examination,ie,qualitative examination,whereas it is diffucult to localize the lesion in AMH compared with pheochromocytoma.The establishment of notion of AMH as an isolated clinicopathological entity broadens and perfects the theory of hypercatecholaminism.
