脾脏肿瘤与非肿瘤性病变的CT鉴别

Differentiation between tumorous and non-tumorous lesions in the spleen on computed tomography

摘要:

目的：探讨脾脏肿瘤与非肿瘤性病变的CT表现及鉴别应用。方法：回顾性分析69例经临床确诊为脾脏病变的CT影像学资料，总结肿瘤性与非肿瘤性病灶影像特征及伴随征象，并采用卡方检验分析相关数据。结果：69例脾脏病变中，肿瘤性病变44例，边界不清者31.8%，出现包膜下积液者4.5%，出现腹膜增厚者2.3%；非肿瘤性病变25例，边界不清者56.0%，出现包膜下积液者60.0%，出现腹膜增厚者24.0%，脾脏肿瘤与非肿瘤性病变在三者的影像表现均有统计学差异（P<0.05）。结论：CT可较清晰地显示脾脏病灶，通过对病灶的边界及伴随征象的分析，有利于对脾脏肿瘤与非肿瘤性病变的鉴别。

Abstract:

Objective：To explore the manifestations of tumorous and non-tumorous lesions in the spleen on computed tomography （CT） and the application of CT in their differentiation. Methods：A retrospective analysis was carried out on the CT data of 69 patients diagnosed with splenic lesions；the imaging characteristics of tumorous and non-tumorous lesions and their accompanying signs were summarized；the chi-square test was used to analyze related data. Results：Among the 69 patients with splenic lesions，44 had tumorous lesions，and 25 had non-tumorous lesions，with the percentages of patients with unclear boundary，subcapsular effusion，and peritoneal thickening to be 31.8%，4.5%，and 2.3%，respectively，in the former population，versus 56.0%，60.0%，and 24.0%，respectively，in the latter population；there were significant differences in the imaging findings of all three pathological changes between the patients with tumorous lesions and non-tumorous lesions（P<0.05）. Conclusion：Splenic lesions can be clearly shown on CT. By analyzing the boundaries of lesions and accompany－ing signs，it is beneficial to differentiate tumorous lesions from non-tumorous lesions in the spleen.
