Extraosseous 99mTc-MDP Accumulation of Left Ureter on Bone Scan: A Case Report

骨骼掃描發現在骨骼外放射活性聚集於左側輸尿管:病例報告

摘要


一位42歲男性十二指腸癌患者,臨床醫師安排核醫骨骼掃描、腹部電腦斷層及腹部超音波做更進一步檢查。核醫骨骼掃描影像發現在左側輸尿管有明顯放射活性聚集。腹部電腦斷層及腹部超音波檢查影像發現左側腎臟輸尿管交接處有鈣化而導致有輕微水腎狀況。綜合臨床檢查結果,我們憶測造成放射活性異常聚集於左側輸尿管原因可能是左側腎臟輸尿管交接處有鈣化狀況。

並列摘要


A 42-year-old man suffered from ampulla's vater cancer of the duodenum. A whole body bone scan, abdominal computed tomography, and abdominal ultrasonography were ordered for him for further evaluation of his cancer. The bone sintigraphy revealed significant accumulation of radiotracer in the left ureter. Both the abdominal computed tomography and the ultrasonography showed calculi at the ureteropelvic junction. Based on the results of his 3 clinical exams, we speculated that the abnormal accumulation of radiotracer in the left ureter may have been caused by calculi at the ureteropelvic junction.
