摘要
目的分析盆腔非生殖源性肿块CT和MRI特征,以提高对该类病变的认识和诊断水平。方法收集2004—2018年中国科学技术大学附属第一医院经手术病理证实的盆腔非生殖源性肿块21例,其中CT检查14例,MRI检查3例,同时行CT及MRI检查4例,分析其CT和MRI表现。结果消化系统来源肿块7例,腹膜外间叶组织来源肿块5例,泌尿系统来源肿块1例,骨胳系统来源肿块1例,其他肿块7例,包括高风险小肠间质瘤6例,小肠B细胞淋巴瘤1例,去分化脂肪肉瘤1例,神经鞘瘤2例,韧带样纤维瘤病1例,恶性孤立性纤维瘤1例,输尿管癌1例,脊索瘤1例,盆腔脓肿2例,表皮样囊肿2例,囊状淋巴管瘤2例,血肿1例。7例囊性肿块均呈良性,大部分边界清楚,密度或信号均匀。9例囊实性肿块及5例实性肿块良恶性均有,以恶性居多,多表现为不均质肿块,且强化明显。结论盆腔非生殖源性肿块临床并不少见,CT和MRI能较清楚显示肿块的位置及其与周边关系,为临床提供有效的诊断信息和依据,具有较高的应用价值。
Objective To study the CT and MRI characteristic of non?genital masses in pelvis and to improve the knowledge of these disease.Methods A total of 21 non?genital masses in pelvis which confirmed by surgery pathology were enrolled in our study from 2004 to 2018.14 patients underwent CT scans,3 patients underwent MRI scans,and 4patients underwent both CT and MRI scans.The CT and MRI imaging findings of masses were analyzed.Results The masses in 7 patients are from digestive sys?tem,5 from extraperitoneal mesenchymal tissue,1 from urinary system,1 from osseous system and 7 from others,including high risk small intestine stromal tumors 6 cases,small intestine B cell lymphoma 1 case,dedifferentiated liposarcoma 1 case,nerve sheath tumor 2 cases,desmoid?type fibromatosis 1 case,malignant solitary fibrous tumor 1 case,ureter carcinoma 1 case,chordoma 1 case,pelvic cavity abscess 2 cases,epidermoid cyst 2 cases,lymphangioma 2 cases and hematoma 1 case.7 cases of cystic mass?es were benign with clear boundary and uniform signal or density.9 cases of cystic solid masses and 5 cases of solid masses were benign or malignant.Most of them were malignantand heterogeneous with obvious enhancement.Conclusion Non?genital masses in pelvis are not uncommon.CT and MRI can clearly show the location and peripheral relations of masses and provide effective diag?nositic information and basis for clinic,which has high application values.
