CT、MR对腹膜后原发肿瘤诊断临床价值分析

摘要

Objective To evaluate the value of CT and MRI in the diagnosis of primary retroperitoneal neoplasms (PRN).Methods The CT findings of 27 PRN were retrospectively analyzied and correlated with surgical and pathologic findings.Results 27 PRN included 11 neurogenic tumour,3 lymphoma,3 malignant fibrous histiocytoma,2 lymphangioma,2 teratoma,2 Liposarcoma,2 leiomyosarcoma,1 lipoma,and 1 epidermoid cyst.21 PRN (84 ％) were correctly diagnosed by CT and MRI,while 6 cases were misdiagnosised.Conclusion CT and MRI were reliable for localization of PRN and essential in making an accurate radiologic diagnosis or narrowing the differential diagnosis.%目的 探讨CT、MR检查对腹膜后肿瘤的诊断价值.方法 对27例腹膜后原发肿瘤患者术前螺旋CT和/或MR进行回顾性分析,并与手术或病理活检的结果进行对照.结果 本组27例中,其中神经源性11例(神经鞘瘤4例,嗜铬细胞瘤3例,神经纤维瘤2例,副神经节瘤1例,神经内分泌瘤1例),淋巴瘤3例,恶性纤维组织细胞瘤3例,淋巴管瘤2例,成熟畸胎瘤2例,脂肪肉瘤2例,平滑肌肉瘤2例,脂肪瘤1例,表皮样囊肿1例.本研究正确诊断腹膜后肿瘤21例(84％),误诊6例.结论 正确识别CT和MR特征性表现对原发腹膜后肿瘤定位、正确诊断或缩窄诊断范围至关重要.
