CT Analysis of Crura of Diaphragm Space Occupying Lesions

Objective Analysing the CT manifestations of the crura of diaphragm space occupying lesions and disucssing the diagnosis and differential diagnosis of lesions.Methods 56 cases of the crura of diaphragm space occupying lesions were observed retrospectively,these lesions were confirmed by clinic and pathology.Results The lesions of crura of diaphragm space followed up:15 cases of spinal metastases;5 cases of spinal tuberculosis;27 cases of lymphadenia;1 case of abdominal aorta false aneurysm;3 cases of azygos vein and semiazygos vein dilatory;1 case of taint caused by esophageal perforation;4 cases of invaded by tumour directly. Conclusion We should recognize the nodes and space of crura of diaphragm correctly,that is helpful to recognize the occupying lesions of crura of diaphragm space properly.
