A 62-year-old man was admitted to our hospital for further examination of right adrenal mass accidentally pointed out by ultrasonogram. He had no symptoms and no physiological abnormalities. Endcrinological examinations revealed normal adrenocortical function, excluding the possibility of functioning adrenocortical adenoma. Pheochromocytoma seemed to be also unlikely since 24-hr urinary excretion of catecholamines were within normal limits. The tumor was surgically removed and histopathologically diagnosed as pheochromocytoma. This case of adrenal incidentaloma is unique in that little sign of pheochromocytoma was presented before operation. The reasons were discussed especially in respect of tissue contents of catecholamines and opioid peptide in comparison with other cases with pheochromocytoma we had experienced.
一名62岁男性因超声意外发现右肾上腺肿块而入院进一步检查。他没有症状，也没有生理异常。内分泌检查显示肾上腺皮质功能正常，排除了功能性肾上腺皮质腺瘤的可能性。由于24小时尿儿茶酚胺排泄量在正常范围内，嗜铬细胞瘤似乎也不太可能。肿瘤通过手术切除，组织病理学诊断为嗜铬细胞瘤。该肾上腺偶发瘤病例的独特之处在于术前几乎没有嗜铬细胞瘤的迹象。我们结合之前遇到的其他嗜铬细胞瘤病例，特别从儿茶酚胺和阿片肽的组织含量方面对原因进行了讨论。
