Extra-adrenal pheochromocytoma causing renal artery stenosis is very uncommon. We describe a patient who had hypertension from this entity. Surgical excision of the mass corrected the renal artery stenosis without the need for bypass grafting, and the patient has remained normotensive. Magnetic resonance imaging (MRI) showed an extremely bright lesion on T2 weighted image, which is virtually pathognomonic. MRI is the most sensitive modality for the detection of an extra-adrenal or unsuspected multiple pheochromocytoma. This should obviate the need for routine abdominal exploration in the evaluation and treatment of pheochromocytoma. Therefore we strongly recommend magnetic resonance imaging in the management of adrenal masses in general and pheochromocytomas in particular.
肾上腺外嗜铬细胞瘤导致肾动脉狭窄非常罕见。我们描述了一名因该疾病患有高血压的患者。手术切除肿块纠正了肾动脉狭窄，无需进行旁路移植，且患者血压一直保持正常。磁共振成像（MRI）在T2加权图像上显示出一个极其明亮的病灶，这几乎具有诊断意义。MRI是检测肾上腺外或未被怀疑的多发性嗜铬细胞瘤最敏感的检查方式。这应该可以避免在嗜铬细胞瘤的评估和治疗中进行常规腹部探查。因此，我们强烈建议在一般肾上腺肿块尤其是嗜铬细胞瘤的管理中使用磁共振成像。
