Abstract:
Intrathoracic mass lesions, especially peripherally situated masses, often present as a problem as tissue diagnosis is not always possible by cytopathological examination. Cutting needle biopsy may be the method of choice in selected cases for tissue diagnosis. Cutting needle biopsy is indicated for patients with peripherally situated mass lesions abutting chest wall, which are non-vascular and non-cystic in nature.
