A case of pheochromocytoma was discovered incidentally during long-term hemodialysis for chronic renal failure due to acquired cystic kidney disease. A 52-year-old male patient was examined for weight loss of 3 kg during over a period of 3 months. Abdominal computed tomography (CT) revealed a left adrenal mass (3.0 cm in size). Plasma adrenaline and noradrenaline were increased to 521 pg/ml and 1,341 pg/ml, respectively, and the metoclopramide provocative test was positive. Further, in the scintiscan using 123I-metaiodobenzylguanidine (MIBG), an accumulation of the radionuclide in the left adrenal tumor region was confirmed. The patient is currently under observation and conservative treatment due to the possible occurrence of arterial hypotension after resection of the tumor and to lesser possibility of the malignancy.
一例嗜铬细胞瘤在因获得性囊性肾病导致慢性肾衰竭进行长期血液透析期间被偶然发现。一名52岁男性患者在3个月内体重减轻了3千克，接受了检查。腹部计算机断层扫描（CT）显示左肾上腺有一个肿块（大小为3.0厘米）。血浆肾上腺素和去甲肾上腺素分别增至521皮克/毫升和1341皮克/毫升，甲氧氯普胺激发试验呈阳性。此外，在使用123I-间碘苄胍（MIBG）的闪烁扫描中，证实放射性核素在左肾上腺肿瘤区域有积聚。由于肿瘤切除后可能发生动脉低血压且恶性可能性较小，该患者目前正在接受观察和保守治疗。
