Abstract
1-123 metaiodobenzylguanidine (1-123 MIBG) scintigraphy is known for its high specificity in detecting pheochromocytoma and other tumors of neural crest origin. In this rare case report, we describe a definite adrenocortical adenoma that demonstrated false-positive uptake at I-123 MIBG scintigraphy and a remarkable accumulation of 75-SE-6-beta-selenomethyl-norcholesterol.
摘要
1-123间碘苄胍（1-123 MIBG）闪烁扫描术以其在检测嗜铬细胞瘤和其他神经嵴起源肿瘤方面的高特异性而闻名。在这份罕见病例报告中，我们描述了一例明确的肾上腺皮质腺瘤，其在I-123 MIBG闪烁扫描术中显示假阳性摄取，并且75-硒-6-β-硒甲基去甲胆固醇有显著积聚。
