Not all mediastinal cysts require puncture biopsy. It is contraindicated if there are contraindications to puncture, but may be performed if the cyst is difficult to diagnose and there are no contraindications.
Puncture biopsy is a useful diagnostic modality for mediastinal cysts, and most mediastinal cysts can be detected as benign or malignant by puncture biopsy. For diseases that are difficult to diagnose and for which there are no relevant contraindications, such as patients with severe bleeding tendency, emphysema, pulmonary heart disease, or cardiac insufficiency, puncture biopsy can be performed to determine its benign or malignant nature.
Whether or not to carry out a puncture biopsy should be under the guidance of the doctor to make the best choice according to the actual condition of the patient, and should not be handled without authorization, in order to avoid accidents.
