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

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.
