A case of a pheochromocytoma in the right adrenal gland and adrenocortical adenoma in the left adrenal gland of a 58-year-old male is reported. The patient was incidentally found to have a right adrenal tumor by ultrasonographic study. A computerized tomographic (CT) study and magnetic resonance image (MRI) study revealed bilateral adrenal tumors. The sizes of the right tumor and left tumor were 2.5 x 3.5 cm and 1.2 x 1.0 cm, respectively. The intensity of each tumor was different on T2-weighted MRI. 131I-MIBG scintigram showed the uptake of right adrenal gland. The existence of pheochromocytoma was confirmed by the elevated levels of catecholamines. We performed venous sampling to be certain whether the patient had unilateral or bilateral pheochromocytoma. As a result, bilateral adrenal pheochromocytoma was diagnosed. Therefore, we performed bilateral adrenalectomy. However, histopathological examination revealed right pheochromocytoma and left non-functioning adrenocortical adenoma.
报告了一例58岁男性患者，其右侧肾上腺嗜铬细胞瘤和左侧肾上腺皮质腺瘤。患者通过超声检查偶然发现右侧肾上腺肿瘤。计算机断层扫描（CT）和磁共振成像（MRI）检查显示双侧肾上腺肿瘤。右侧肿瘤和左侧肿瘤的大小分别为2.5×3.5厘米和1.2×1.0厘米。在T2加权MRI上，每个肿瘤的信号强度不同。131I-MIBG闪烁扫描显示右侧肾上腺有摄取。儿茶酚胺水平升高证实了嗜铬细胞瘤的存在。我们进行了静脉采样以确定患者是单侧还是双侧嗜铬细胞瘤。结果，诊断为双侧肾上腺嗜铬细胞瘤。因此，我们进行了双侧肾上腺切除术。然而，组织病理学检查显示右侧为嗜铬细胞瘤，左侧为无功能肾上腺皮质腺瘤。
