title: Tru-Cut biopsy of mediastinal masses guided by real-time sonography.
abstract: Twenty-five patients with mediastinal masses, arising in the anterior, middle and posterior mediastinum but in contact with the chest wall, underwent ultrasound (US) guided biopsy with a Tru-Cut needle to obtain a core biopsy specimen from the mass. In all these patients adequate tissue was obtained for a histopathological diagnosis and no major complications were observed. The advantage of core biopsy over fine needle aspiration cytology in mediastinal masses is that accurate histopathological differentiation, and classification of carcinomas and lymphomas is possible. The advantage of performing real-time US guided biopsy is that puncture of the lung and mediastinal vascular structures is avoided.
