Postoperative CT of thymoma shows bilateral pleural thickening, which is not thymoma recurrence in general, and is generally considered to be bilateral pleural thickening caused by fibrinous exudation, granulation tissue proliferation caused by postoperative pleural inflammation of thymoma, and hemorrhage mechanization of the residual thoracic cavity at the time of surgery.
1. Thymoma often invades mediastinal pleura and pleural and pericardial metastasis, postoperative pleural metastasis and recurrence of thymoma mainly manifested as chest pain, pleural effusion and local hemispherical or irregular uniform soft tissue density shadow in the pleura, and there is usually no bilateral pleural thickening.
2. Postoperative CT of thymoma showed that bilateral pleural thickening was generally hypertrophy of wall pleura, which was caused by fibrinous exudation, granulation tissue hyperplasia due to postoperative pleural inflammation of thymoma, as well as residual pleural hemorrhage mechanization during surgery, etc., and was generally unrelated to the recurrence of thymoma.
Whether the bilateral pleural thickening shown by CT after thymoma surgery is recurrence or not, it is recommended to go to the hospital for further consultation, examination or treatment.
