目的：探讨输尿管海绵状血管瘤并血栓形成的影像学特征，提高影像诊断准确率。方法回顾性分析误诊为输尿管癌的输尿管海绵状血管瘤并血栓形成1例的临床资料，并复习相关文献。结果本例因发现肉眼血尿伴尿急、尿痛2周入院。行静脉肾盂造影及泌尿系增强CT发现其影像学表现与输尿管恶性肿瘤相似，误诊为输尿管癌，行手术治疗。术后病理诊断为输尿管海绵状血管瘤并血栓形成，予对症及营养支持治疗后痊愈出院。半年后随访病灶未见复发。结论输尿管海绵状血管瘤临床较少见，如合并血栓形成影像学表现类似恶性肿瘤，易误诊，临床应高度警惕。%Objective To investigate imaging features of ureteral cavernous hemangioma so as to improve diagnostic rate of imaging. Methods Clinical data of one patient with ureteral cavernous hemangioma misdiagnosed as having ureteral carcinoma was retrospectively analyzed, and relevant literature was also reviewed. Results The patient was admitted for mac-roscopic hematuria associated by urgent micturition and odynuria for 2 weeks. Intravenous pyelography and enhanced CT showed similar imaging with ureteral malignant neoplasm, and the patient was misdiagnosed as having ureteral carcinoma, and the surgery was performed. Postoperatively pathological diagnosis was ureteral cavernous hemangioma combined with thrombo-sis, and the patient was discharged after recovery by symptomatic treatment and nutritional support, and no recurrence was found by follow-up after discharging for half a year. Conclusion Ureteral cavernous hemangioma is rare, and it is easy to be misdiagnosed as malignant tumor when it combines with thrombosis in similar imaging findings, and therefore clinicians should pay more attention.
