title: [MDCT features and anatomic-pathological basis of the diseases in central thoracic-abdominal junctional region].
abstract: This paper is to determine relationship between MDCT features and anatomic-pathology of the diseases in central thoracic-abdominal junctional region. 3 cadavers were cut transversely and another 3 vertically to observe the anatomy of thoracic-abdominal junctional zone. 93 patients with diseases in central thoracic-abdominal junctional zone were scanned with MDCT. The correlation between MDCT features of the diseases in central thoracic-abdominal junctional region and the anatomic-pathology of the diseases in this region was evaluated. On cadaver sections, central thoracic-abdominal junctional region was an area between anterior chest wall and dorsal spine in vertical direction. The region was separated into upper and lower sections by diaphragm. The upper section mainly contains heart and pericardium, while the lower contains broad ligament and left lobe of liver. The hiatus of diaphragm are vena caval foramen, esophageal foramen and aortic foramen in anterior-posterior turn. In the present study, 23 patients had portal hypertension, 18 had dissection of aorta, 8 got diseases in inferior vena cava, 9 had lymphoma, 12 got diseases in multiple vertebrae, 7 had lower thoracic esophageal carcinoma accompanied with metastasis in upper abdominal lymph nodes, 9 had carcinoma of abdominal esophagus and/or gastric cardia, 4 had esophageal hiatal hernia and 3 patients had neurogenic tumor in posterior mediastinum and/or superior spatium retroperitoneale. The MDCT features and distribution of the diseases in central thoracic-abdominal junctional region influence the anatomic-pathology characteristics in this region.
