Three cases of urachal carcinoma are reported with special reference to the preoperative capability of computed tomography (CT) to establish the tumor origin in 2 patients. A midline anterior abdominal mass relating to the dome of the urinary bladder on CT together with a history of hematuria is suggestive of the diagnosis. The post-operative manifestation on CT is also described.
台大醫院發現三例臍尿管癌病例,其中兩例在手術前作電腦斷層掃描獲得正確診斷:一例爲前腹壁囊狀腫塊,經電腦斷層矢狀切面後,更清晰地看到其源自肚臍延伸至膀胱頂,故矢狀切面係診斷此病灶要素,卻未見文獻提及。另外一例爲較小的臍尿管癌,3×3公分大小,含鈣化點管狀腫塊自膀胱前頂端向前腹壁延伸;是文獻裡最小的臍尿管癌在電腦斷層的表現。
