目的探讨盆腔淋巴结清扫术后淋巴囊肿形成的CT诊断价值。资料与方法回顾性分析经手术或穿刺病理证实的37例盆腔淋巴囊肿患者的CT表现。所有病例均行B超及CT平扫检查,29例行CT增强,11例行CT复查。结果28例在手术后15天～3个月内的首次CT检查时发现。19例发生在双侧,7例单发于右侧,11例单发于左侧。囊肿直径约2.4～6.0 cm。6例合并感染者形态不规则,密度不均匀,与周围组织粘连。CT发现率100%,诊断准确率86.5%(32/37)。结论多层螺旋CT可以清晰显示淋巴囊肿的形态学特征、部位及与周围组织的关系,结合临床可提高其诊断准确率。
Objective To investigate the value of CT in the diagnosis of lymphatic cyst after pelvic lymph node dissection. Materials and Methods Retrospective analysis of CT findings of 37 cases of pelvic lymphatic cysts confirmed by surgery or biopsy. All cases underwent B-scan and CT plain scan, 29 cases of CT enhancement, 11 cases of CT review. Results 28 cases were found at the first CT examination within 15 days to 3 months after operation. 19 cases occurred on both sides, 7 cases were solitary on the right side and 11 cases were solitary on the left side. Cyst diameter of about 2.4 ~ 6.0 cm. Six cases of co-infected patients with irregular shape, uneven density, adhesions with the surrounding tissue. The detection rate of CT was 100% and the diagnostic accuracy was 86.5% (32/37). Conclusions Multi-slice spiral CT can clearly show the morphological features, location of the lymphatic cyst and the relationship with the surrounding tissues, and improve the diagnosis accuracy with clinical diagnosis.
