目的：探讨脐尿管癌的多层螺旋CT（MSCT）表现，提高对该病的诊断水平。方法：回顾性分析8例脐尿管癌的MSCT表现，包括肿块的部位、形态、密度、增强特点、局部侵犯和转移，并与术后病理结果对照。结果：8例脐尿管癌在MSCT上均表现为位于脐尿管走行区的中线肿块，7例呈囊实性，1例呈实性，5例肿块内见钙化，增强扫描后所有肿块呈不均匀强化。膀胱黏膜受侵7例，表现为膀胱腔内不规则肿块。结论：脐尿管癌有其独特的发生部位和较为典型的影像学表现，MSCT有助于对其进行正确的术前诊断。
Abstract
Objective: To discuss findings of urachal carcinoma by MSCT, and improve the ability for the diagnostic level of the disease. Methods: The MSCT findings of eight cases with surgically proven urachal carcinomas were retrospectively reviewed. CT images were evaluated to determine tumor localization, morphology, density, enhanced pattern, extent of local invasion and metastases, and compared with pathology. Results: MSCT in all eight cases showed a mass located in the midline between the dome of the bladder and the umbilicus. Seven cases were mixed cystic solid lesions and one case was completely solid. Calcifications were present in five cases. All lesions showed heterogeneous enhancement after contrast administration. Bladder mucosal invasion was present in seven cases, was seen as an intra luminal irregular mass. Conclusion: MSCT examination before surgery is useful to correctly diagnose of urachal carcinoma which showed unique location and characteristic imaging findings.
