Objective To investigate the diagnostic value of 7-zone imaging for ectopic thymoma. Methods Eleven cases of patients with ectopic thymoma confirmed by biopsy and surgical pathology were studied by imaging findings and surgical findings of chest radiograph, CT and MRI. Results 11 cases of ectopic thymoma mediastinal 9 partition method were located in the left middle and lower middle and lower mediastinum in 3 cases, the right middle and lower middle mediastinal in 4 cases, the right side of the anterior mediastinal in 4 cases. 11 cases in the mediastinal 7 partition method in the anterior mediastinal. Conclusion The mediastinal 7-zone method has obvious value in the diagnosis of thymoma, which is of great significance for the clear surgical resection.
