Abstract:
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.
