摘要
目的：探讨脐尿管癌的影像表现及其病理特点，评价其临床诊断价值。方法：收集经手术病理证实的4例脐尿管癌的影像资料，回顾性分析病灶的影像特点并与组织病理学特征相对照。结果：4例脐尿管癌患者的病变部位均在腹中线Retzius间隙脐尿管走行区，其中3例位于脐尿管膀胱交界区的膀胱顶壁或前壁，1例位于脐尿管上端，4例脐尿管癌中1例实性，3例囊实性，4例病灶中心或周边见斑点状钙化。增强扫描后所有病灶均有不同程度强化。结论：脐尿管癌的影像表现对脐尿管癌的定位定性诊断以及手术计划的制定具有重要价值。
Abstract
Objective: To investigate pathologic characteristics and the value of imaging findings in diagnosing urachal carcinoma. Methods: The imaging findings in 4 cases examined by CT or MRI with pathologically-proved urachal carcinoma were collected. The image characteristics were retrospectively analyzed and compared with histological features. Results: In the 4 cases of urachal carcinoma, the foci observed in CT or MRI imaging were located at the urachal area in the Retzius space of mid-abdominal line, with 3 cases on the top or anterior wall of the bladder at urachus-bladder junction, 1 case at the upper end of urachus. Among the 4 cases of urachal carcinoma, there was 1 case with solid changes, and 3 cases with cystic changes. All the cases had central or peripheral dotted calcification. All the 4 cases showed different degrees of enhancement. Conclusion: CT or MRI is an effective imaging modality in the localization and qualitative diagnosis of urachal carcinoma. Moreover, it can provide more anatomical information for surgery.
