I-131 metaiodobenzylguanidine scintigraphy showed marked accumulation in the walls of a clinically silent, huge cystic adrenal mass with a prominent hemorrhage in a 48-year-old man. Although a careful reexamination of the histologic specimen finally lead to a diagnosis of pheochromocytoma, the appearances of this mass on computed tomography and magnetic resonance imaging were not specific for this neoplasm, and even pathologic analysis initially indicated, incorrectly, that this lesion was a hemorrhagic hemangioma. This case shows that I-131 metaiodobenzylguanidine scintigraphy is useful for correctly diagnosing an adrenal mass with prominent cystic or hemorrhagic degeneration.
碘-131间碘苄胍闪烁扫描显示，一名48岁男性临床无症状的巨大囊性肾上腺肿块壁上有明显放射性浓聚，伴有显著出血。尽管对组织学标本进行仔细复查最终诊断为嗜铬细胞瘤，但该肿块在计算机断层扫描和磁共振成像上的表现对这种肿瘤并不具有特异性，甚至病理分析最初错误地表明该病变是出血性血管瘤。该病例表明，碘-131间碘苄胍闪烁扫描有助于正确诊断具有显著囊性或出血性退变的肾上腺肿块。
