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.
脐尿管是一种中线管状结构，它在膀胱顶部和脐之间延伸，是正常发育过程中不完全退化的结果。脐尿管闭锁不全很少见，可导致脐尿管异常，最常见的是恶性肿块。黄色肉芽肿性脐尿管肿块是慢性炎症过程的罕见形式，仅有少数病例报道。由于缺乏典型的临床和影像学表现，加上诊断经验或认知有限，区分脐尿管良性病变和恶性病变具有挑战性。我们报告一例脐尿管癌的初始误诊病例，术后组织病理学检查显示为良性脐尿管黄色肉芽肿性炎症。
