Abstract

We report a patient with DTPA and DMSA uptake on unsuspected bone metastases. He had severe pain due to grade 3 hydronephrosis of his left kidney. When Tc-99m DTPA and DMSA renal scanning were performed for preoperative evaluation, abnormal radiopharmaceutical uptake on the iliac area was noted. Pancreatic adenocarcinoma metastases to bone were subsequently defined. This patient is a very demonstrative case in respect of having all DTPA, DMSA and HDP uptakes in bone metastases. The type of the tumor has to be added to the list of extrarenal uptake of DTPA and DMSA as a rare cause.

摘要

我们报告了一例在未被怀疑有骨转移的情况下出现二乙三胺五乙酸（DTPA）和二巯基丁二酸（DMSA）摄取的患者。他因左肾3级肾积水而疼痛剧烈。在进行术前评估而行锝-99m DTPA和DMSA肾扫描时，发现髂骨区域有异常放射性药物摄取。随后确定为胰腺腺癌骨转移。就骨转移中出现所有DTPA、DMSA和羟基亚甲基二膦酸盐（HDP）摄取而言，该患者是一个极具代表性的病例。作为一种罕见原因，肿瘤类型必须添加到DTPA和DMSA肾外摄取的列表中。
