Esophageal stromal tumors:comparison of radiologic findings and pathology

LIU Jian,WANG Zhu,QU Dong(Department of Diagnostic Radiology,Chinese Academy of Medical Science,Beijing Union Medical College,Beijing 100021,China)  
Objective Analyze the clinical and imaging feature of esophagus stromal tumor to approach the diagnostic value of esophageal imaging and CT(computed tomography) to esophageal stromal tumors.Methods A retrospective analysis about 12 pathologically confirmed cases of esophageal stromal tumors of the clinical data,and esophageal imaging and CT findings with surgical and pathological findings were compared to explore the esophagus imaging and CT angiography features with relation to pathological basis.Results 12 patients with 13 lesions were detected,11 cases of single lesion,1 case of 2 lesions.Within 13 lesions,there are 4 cases for very low degree of risk of tumor invasion,four for the low risk of tumor invasion,one of amoderate risk of tumor invasion,four for high risk of tumor invasion.Esophageal stromal tumors with very low and low degree of risk of invasion performance of the external pressure of the esophagus changes or curved over smooth filling defect on esophageal imaging,and show round-homogeneous soft tissue density,mild enhanced on CT scan.Esophageal stromal tumors with moderate and high risk of invasion show esophageal wall stiffness and mucosa damage on esophageal imaging,and can be seen the cystic necrosis and irregular enhancement on CT scan.Conclusion Esophageal stromal tumors of different risk of invasion have some differences on esophageal imaging and CT,which is valuable for the diagnosis of esophageal stromal tumor and classification of risk of invasion,but the final diagnosis depends on pathologic diagnosis.
