Aim: To report our experience with computed tomography (CT)-guided coaxial needle biopsy of intra-thoracic lesions by different approaches. Place and Duration: In the Radiology department of Jinnah Hospital Lahore foe one year duration from March 2019 to March 2020. Material and Methods: Medical records of 100 patients who underwent a thoracic biopsy were reviewed retrospectively. Coaxial needle technique was used in all patients; A 18-gauge needle was used for transdermal penetration, and a thin needle was passed through the 22-gauge needle for aspiration. A core-needle biopsy was performed on five patients by placing 20-gauge needles coaxially. Medical records were reviewed to determine the size and location of the lesion, needle trajectory, and number of needle penetrations, causes of failure, biopsy results, and complications. Results: The trans-sternal approach was used in mediastinal (n = 32) or intrapulmonary (n = 5) lesions. Extrapleural access to the mediastinal lesions was achieved in all but one patient in whom the 22-gauge needle traversed the lung. Conclusion: CT-guided coaxial core-needle biopsy ensures safe access to masses in various parts of the chest and anteroposterior lung. Keywords: Needle biopsy, computed tomography, Intrathoracic.
