Abstract

The authors present a case of extraskeletal myxoid chondrosarcoma. The MR study clearly showed the extent of the tumor and a "rings and arcs" pattern appeared after Gadolinium-DTPA administration in the T1 weighted images. Dynamic Tc-99m MDP and Tc-99m DTPA scintigraphy showed increased blood flow in the mass. The delayed 3-hour images demonstrated moderate Tc-99m MDP uptake, but intense Tc-99m DTPA accumulation in the tumor. Surprisingly, the Ga-67 scan failed to demonstrate the tumor.

摘要

作者报告了1例骨外黏液样软骨肉瘤病例。磁共振成像（MR）研究清楚地显示了肿瘤范围，钆喷酸葡胺（Gadolinium-DTPA）注射后T1加权像上出现“环状和弧形”表现。动态锝-99m亚甲基二膦酸盐（Tc-99m MDP）和锝-99m二乙三胺五醋酸（Tc-99m DTPA）闪烁显像显示肿块内血流增加。3小时延迟显像显示Tc-99m MDP摄取中等，但肿瘤内有强烈的Tc-99m DTPA聚集。令人惊讶的是，镓-67扫描未显示出肿瘤。
