42例外围性子宫内膜异位症患者MSCT影像学特征及临床病理分析

MSCT Imaging Characteristics and Clinical Pathology of 42 Patients with Peripheral EM

目的总结外围性EM患者MSCT影像学特征及临床病理,旨在为临床诊断治疗提供参考。方法收集本院2017年9月至2019年9月收治的42例外围性EM患者的临床资料作为研究对象,对患者所得MSCT图像进行分析,了解患者病灶大小、位置、周围组织情况、病灶密度等,与临床病理结果进行对照分析。结果MSCT表现:实质型:平扫为软组织密度,边缘可见分叶,并见有“纤维条索”状影伸向四周。平扫密度较均匀,增强呈轻中度强化;囊肿型:可为多房囊肿,也可为单房囊肿,囊壁多较厚,增强扫描囊壁有一定程度强化;囊实混合型:同时有实质型与囊肿型的CT表现。病理:其由纤维组织组成,内部血管间可见有淋巴细胞、浆细胞、含铁血黄素颗粒、少量的宫内膜腺体组织。结论外围性EM患者的MSCT表现存在一定特征性,了解其病理基础,在临床诊断中结合患者临床表现可有效提高其临床诊断率。

Objective To summarize the MSCT imaging characteristics and clinical pathology of patients with peripheral EM,in order to provide reference for clinical diagnosis and treatment.Methods The clinical data of 42 patients with peripheral EM treated in our hospital from September 2017 to September 2019 were collected as the research object.The MSCT images of the patients were analyzed to understand the size,location,surrounding tissues,and density of the lesion,and so on.To compare and analyze the MSCT images with clinicopathological results.Results MSCT showed that for parenchymal type,plain scan showed the density of soft tissues,lobes were visible at the edges,there were shadows like"fiber strands"stretching all around,the density of the plain scan was relatively uniform,and the enhanced scan shows mild to moderate enhancement.For cyst type,it can be multilocular cyst or unilocular cyst.The cyst wall was thicker,and the cyst wall was enhanced to a certain extent in the enhanced scan.For cystic and solid mixed type:CT manifestations are both parenchymal and cystic.Pathology:It is composed of fibrous tissue.Lymphocytes,plasma cells,hemosiderin granules,and a small amount of endometrial glandular tissue were seen in the internal blood vessels.Conclusion The MSCT manifestations of peripheral EM patients have some characteristics.Understanding their pathological basis and combining clinical manifestations of patients in clinical diagnosis can effectively improve their clinical diagnosis rate.
