Tc-99m DTPA scintigraphy of most renal tumors characteristically discloses a vascular mass, without retention of activity on serial images. Two cases, encountered during hypertensive work-up, are presented with vascular renal masses and persistent DTPA uptake. Oncocytoma was confirmed pathologically in both cases. The authors conclude that renal oncocytomas have a relatively distinctive scintigraphic appearance, which may permit accurate preoperative diagnosis.
大多数肾肿瘤的锝-99m二乙三胺五乙酸闪烁扫描特征性地显示为血管性肿块，在系列图像上无放射性滞留。本文报告了在高血压检查过程中遇到的2例病例，均有肾血管性肿块且二乙三胺五乙酸持续摄取。2例病例经病理证实均为嗜酸细胞瘤。作者得出结论，肾嗜酸细胞瘤具有相对独特的闪烁扫描表现，这可能有助于术前准确诊断。
