Abstract :
Aims and Objectives:
This study aims to evaluate the safety and efficacy of CT-guided transsternal core biopsy for anterior mediastinal masses, particularly in cases where traditional parasternal approaches may pose significant risks, such as injury to the internal mammary artery leading to life-threatening hemothorax.
Methods:
We conducted CT-guided percutaneous transsternal core biopsies on two patients with anterior mediastinal masses. The procedure involved local anesthesia using 10 cc of 2% Lignocaine, followed by the insertion of a bone biopsy needle to penetrate the sternum and reach the anterior mediastinum. A Bard Tru-Cut semiautomatic core biopsy needle was then employed to collect 3-5 adequate core samples. The biopsy sites were subsequently dressed with Betadine.
Results:
In the first case, a 55-year-old male presented with a mass in the apical and anterior segment of the right upper lobe extending into the anterior mediastinum. The biopsy yielded a diagnosis of small cell lung cancer, with no procedure-related complications. The second case involved a 73-year-old male with a large anterior and superior mediastinal mass, which was diagnosed as ALK-negative anaplastic large cell lymphoma, also without any complications during the procedure.
Conclusions:
CT-guided transsternal core biopsy is a safe and effective technique for accessing anterior mediastinal masses. It offers advantages over the parasternal approach, including a reduced risk of vascular injury and complications such as hemothorax and pneumothorax. Our findings support the use of this method in clinical practice for obtaining tissue samples from difficult-to-reach anterior mediastinal lesions.
