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、MRI征象
Objective To investigate the CT and MRI diagnosis and anatomy of thoraco-abdominal communicating lesions. Materials and Methods Retrospective analysis of 54 cases of thoracoabdominal communicating through the diaphragm and diaphragmatic lesions, and 40 cases of normal CT, MRI performance as a control. Results Eighteen cases of esophageal fissure were found in 54 cases. The main lesion was gastric cardia invasion of the lower esophagus, esophageal varices and esophageal hernia. Twenty-one cases had aplastic aorta with lesions of lymphoma, lymphatic metastasis, other tumors, Venous obstruction after the expansion of azygos vein; the inferior vena cava hole in 7 cases; the diaphragm directly through the 8 cases, found in lung cancer, liver cancer, infectious diseases, congenital dysplasia and trauma and so on. Conclusion Proficiency in the normal anatomy of the phrenic hole helps to accurately identify CT and MRI signs of thoraco-abdominal lesions
