原发常见腹盆腔、腹膜后肿瘤CT诊断及鉴别诊断
|
摘要
目的:探讨常见原发腹盆腔、腹膜后肿瘤CT影像特征。方法:回顾性分析56例病理证实的原发腹盆腔、腹膜后肿瘤的CT资料,结合文献进行CT影像表现探讨。结果:(1)56例病例中:巨淋巴结增生症6例,孤立性纤维性肿瘤7例,胃肠道外间质瘤15例,副神经节瘤16例,平滑肌肉瘤12例。(2)5组病例病灶强化程度△CT(HU)从大到小分别为孤立性纤维性肿瘤(81.43±36.50HU),巨淋巴结增生症(60.83±8.08 HU),副神经节瘤(53.81±30.34 HU),胃肠道外间质瘤(36.13±10.06 HU),平滑肌肉瘤(30.75±7.61 HU);其中,巨淋巴结增生症与孤立性纤维性肿瘤组间P值为0.10、巨淋巴结增生症与副神经节瘤组间P值为0.50,胃肠道外间质瘤与平滑肌肉瘤组间P值为0.53,其余各组间P值均小于0.01。结论:原发腹盆腔、腹膜后肿瘤具有一定的CT影像征象特点,CT对肿瘤的定位定性诊断有重要价值。
Objectives To investigate the computed tomography[CT]features of primary abdominal and pelvic tumors,and retroperitoneal tumors,Methods 56 patients with pathologically proved primary abdominal and pelvic tumors and retroperitoneal tumors were retrospectively enrolled,all patients were examined by multiphase enhanced CT scan.ANOVA analysis was used for comparison of CT enhancement degree between groups.Results Among 56 cases,6 cases were giant lymph node hyperplasia,7 cases were solitary fibrous tumors,15 cases were extra-gastrointestinal stromal tumors,16 cases were paraganglioma and 12 cases were leiomyosarcoma TheACT(Hu),which means the enhancement degree of tumor lesions,was different between groups in CT scans:solitaryfibrous tumors(81.43±36.50),giant lymph node hyperplasia(60.83±8.08),paraganglioma(53.81±30.34),extra-gastrointestinal stromal tumors[36.13±10.06],leiomyosarcoma[30.75±7.61],respectively.The P value was 0.10 between giant lymph node hyperplasia and solitary fibrous tumors,0.50 between giant lymph node hyperplasia and paragangliomaand 0.53 between extra-gastrointestinal stromal tumors and leiomyosarcoma,respectively.No significant differences were found between these compared groups.However,the P values were all less than 0.01 among the other compared groups.Conclusions Primary abdominal and pelvic tumors and retroperitoneal tumors have unique CT imaging features.CT scanshave important values in the localization and qualitative diagnosis of these tumors.
