摘　　要：目的　探讨胸腹通连病变的CT、MRI诊断及其解剖基础。材料与方法　回顾性分析 5 4例穿越膈孔和膈肌的胸腹通连病变 ,并以 40例正常人CT、MRI表现作对照。结果　 5 4例病变中经食管裂孔 18例 ,病变主要系贲门癌侵犯食管下段、食管静脉曲张及食管旁疝 ;经主动脉裂孔 2 1例 ,病变有淋巴瘤、淋巴转移、其他肿瘤及上腔静脉阻塞后奇静脉扩张 ;经下腔静脉裂孔 7例 ;经膈肌直接穿通 8例 ,见于肺癌、肝癌、感染性疾病、先天性膈发育异常和外伤等。结论　熟练掌握膈孔的正常解剖有助于准确认识胸腹通连病变的CT。Objective To evaluate CT and MRI findings in diagnosing thoraxabdomen communicating diseases, and to study their anatomic basis.Materials and Methods CT and MRI were performed in 40 normal subjects and 54 patients with thoraxabdomen communicating diseases.Results Of total 54 patients, 18 lesions passed through the esophageal aperture, including cardiac carcinoma with invasion of lower esophagus, parasophageal varices or hiatus hernia; 21 lesions passed through the aortic aperture, including lymphoma, lymphatic metastasis, other tumors and dilatation of azygous vein due to SVC obstruction; 8 lesions passed through diaphragm directly, including lung cancer, HCC infection congenital malformation of the diaphragm.Conclusion For a better understanding of the CT and MRI signs of the thoraxabdomen communicating lesions, to be familiar with the normal anatomy of the diaphragmatic apertures is very helpful.
