The patient, a 59-year-old woman, was referred to our University Hospital for evaluation of a left mass. Ultrasonography revealed a left adrenal cystic mass. On excretory urograms, the left kidney was pressed downward by a suprarenal mass, and computerized tomography (CT) and magnetic resonance imaging (MRI) confirmed an adrenal cyst. 131I-meta-iodo-benzylguanidine (MIBG) scintigraphy showed prominent accumulation in the left adrenal mass and the capsule. Considering the elevation of catecholamines in both blood and urine samples, we performed a left adrenalectomy with a presumptive diagnosis of pheochromocytoma (tumor size: 11.6 x 7.5 x 6.5 cm, tumor weight 720 g). The subsequent pathological examination confirmed a left giant cystic pheochromocytoma. 131I-MIBG scintigraphy was the most useful tool in the diagnosis of the cystic pheochromocytoma.
该患者为一名59岁女性，因左侧肿块前来我院评估。超声检查发现左侧肾上腺囊性肿块。排泄性尿路造影显示左肾被肾上腺肿块向下压迫，计算机断层扫描（CT）和磁共振成像（MRI）证实为肾上腺囊肿。131I-间碘苄胍（MIBG）闪烁显像显示左侧肾上腺肿块及包膜有明显放射性浓聚。考虑到血液和尿液样本中儿茶酚胺升高，我们进行了左侧肾上腺切除术，初步诊断为嗜铬细胞瘤（肿瘤大小：11.6×7.5×6.5 cm，肿瘤重量720 g）。随后的病理检查证实为左侧巨大囊性嗜铬细胞瘤。131I-MIBG闪烁显像在囊性嗜铬细胞瘤的诊断中是最有用的工具。
