Two cases of rare urachal anomalies in the adult are described, including one acquired patent urachus and one giant urachal cyst. The presenting symptoms and signs included pyuria, fever, lower abdominal pain and palpable abdominal mass. The correct preoperative diagnosis was made after sonography. The clinical and radiographic features and magnetic resonance imaging are presented. Stone formation and the huge capacity of the urachal cyst are first reported. Excision of the urachal tract with resection of the bladder dome and cauterization of the cystic wall with stone removal were performed in that order. When a young adult presenting with a wet umbilicus, acute abdominal pain or a lower midline abdominal mass, the possibility of an infected urachal anomaly should be considered in the differential diagnosis.
本文描述了两例成人罕见的脐尿管异常病例，其中一例为后天性脐尿管未闭，另一例为巨大脐尿管囊肿。主要症状和体征包括脓尿、发热、下腹部疼痛和可触及的腹部肿块。超声检查后做出了正确的术前诊断。文中介绍了其临床、影像学特征及磁共振成像表现。首次报道了结石形成及脐尿管囊肿的巨大容量。依次进行了脐尿管切除、膀胱顶部切除及囊肿壁烧灼并取出结石。当年轻成人出现脐部潮湿、急性腹痛或下腹部中线肿块时，鉴别诊断中应考虑感染性脐尿管异常的可能性。
