Abstract：
The urachus is a midline tubular structure that extend between bladder dome and umbilicus which result from incomplete regression during normal development. Defective obliteration of the urachus is rare and can result in urachal abnormalities, most commonly malignant masses. Xanthogranulomatous urachal masses are rare forms of chronic inflammatory processes with only few reported cases. Differentiating malignant from benign urachal lesion is challenging due to lack of typical clinical and radiologic manifestations, coupled with limited diagnostic experience or awareness. We present an initial misdiagnosis of urachal carcinoma, which was revealed to be benign xanthogranulomatous inflammation of urachus on postoperative histopathological examination.
摘要：
脐汁是在膀胱穹顶和脐部之间延伸的中线管状结构，这是由于正常发育过程中的不完全消退所致。脐尿管有缺陷的闭塞是罕见的，可导致脐尿管异常，最常见的恶性肿块。黄色肉芽肿性脐尿管肿块是慢性炎症过程的罕见形式，仅报道了很少的病例。由于缺乏典型的临床和影像学表现，区分恶性和良性脐尿管病变具有挑战性。加上有限的诊断经验或意识。我们提出了脐尿管癌的初步误诊，术后组织病理学检查显示为脐尿管良性黄色肉芽肿性炎症。
