[Needle biopsy in diagnosing primary mediastinal tumors]
Aim:
To assess the potential of biopsies with the thick cutting needle of anterior mediastinum tumor.
Material And Methods:
Biopsy with the use of the thick cutting needle (Baxter Healthcare Corporation, length 150 mm, thickness 2.5 mm, length of the cutting channel 20 mm) of a primary mediastinal tumor was made in 12 patients.
Results:
The findings were the following: 8 cases of primary mediastinal B-cell lymphosarcoma, 1 case of T-cell lymphosarcoma with involvement of the mediastinum, 2 cases of thymic carcinoma, 1 case of pituitary tumor. Mediastinal puncture was controlled by ultrasound which secured accurate position of the needle and safe conduction of the puncture.
Conclusion:
Puncture biopsy with the thick cutting needle of anterior mediastinum tumor provides short duration of the diagnostic process and correction of the treatment policy.
