A 72-year-old man was admitted with a lower abdominal mass, occasionally detected during a previous laparoscopy. The cystoscopy revealed a bulging mass 5 cm in diameter at the vesical dome. The computed tomography (CT) scan showed an extravescical extension in close relationship with the posterior abdominal wall. Two consecutive endoscopic biopsies and a CT-guided percutaneous biopsy were not helpful. At surgery, a mass about 10 cm in diameter was found at the vesical dome and removed "en-block". The microscopic examination showed a chronic urachal abscess. To our knowledge, this is the second case of asymptomatic urachal abcess mimicking a bladder neoplasm. The reasons of a surgical approach are discussed.
一名72岁男性因下腹部肿块入院，该肿块在之前的腹腔镜检查中偶尔被发现。膀胱镜检查显示膀胱顶部有一个直径5厘米的隆起肿块。计算机断层扫描（CT）显示肿块向膀胱外延伸，与后腹壁关系密切。连续两次内镜活检和一次CT引导下经皮活检均未明确诊断。手术中，在膀胱顶部发现一个直径约10厘米的肿块，并将其整块切除。显微镜检查显示为慢性脐尿管脓肿。据我们所知，这是第二例无症状脐尿管脓肿酷似膀胱肿瘤的病例。本文讨论了采用手术治疗的原因。
