An 85-year-old woman with leiomyosarcoma occupying the abdominopelvic area had a renal dynamic study with Tc-99m DTPA. The tumor area initially showed almost no content of the radiopharmaceutical. At 24 hours, there was retention of activity in the leiomyosarcoma as compared with surrounding tissues (flip flop). It was noted that, based on literature reports, tumors of mesodermal origin (leiomyoma, spindle cell sarcoma, neurofibroma) may have the ability to concentrate Tc-99m DTPA.
一名85岁的女性，腹盆腔区域患有平滑肌肉瘤，接受了用锝-99m二乙三胺五醋酸（Tc-99m DTPA）进行的肾动态研究。肿瘤区域最初几乎没有放射性药物摄取。24小时时，与周围组织相比，平滑肌肉瘤内有放射性活性滞留（即“翻转”现象）。据文献报道，注意到中胚层起源的肿瘤（平滑肌瘤、梭形细胞肉瘤、神经纤维瘤）可能具有摄取Tc-99m DTPA的能力。
