Abstract

Unanticipated but clinically significant nonosseous findings can be detected during routine bone scintigraphy. We present a case of an 83-year-old man who presented with a pathologic fracture of the right femur. Whole-body bone scintigraphy for osseous staging revealed intense radiotracer accumulation in the kidneys and ureters but no activity within the urinary bladder. The patient had not voided for 14 hours. A Foley catheter was inserted, and more than 2000 mL of urine was drained, most consistent with urinary bladder obstruction. Subsequent repeat images demonstrated marked reduction of the renal and ureteral activity with trace activity in the urinary bladder.

摘要

在常规骨扫描期间，可能会发现意外但具有临床意义的非骨性发现。我们报告了一例 83 岁男性，其因右侧股骨病理性骨折就诊。全身骨扫描进行骨分期显示肾脏和输尿管有强烈的放射性示踪剂积聚，但膀胱内无活性。患者已经 14 小时未排尿。插入了 Foley 导管，并排出了超过 2000 毫升的尿液，最符合膀胱梗阻的情况。随后的重复图像显示肾脏和输尿管的活性明显降低，膀胱内仅有微量活性。
