摘要: Abstract OBJECTIVE: Interest has been growing in using endoscopic ultrasound and ultrasound-guided fine needle aspiration the evaluation of mediastinal masses. The purpose this study was to review spectrum masses encountered ultrasound. METHODS: We reviewed all cases examined by ultrasound, with or without aspiration, prospectively gathered from our electronic database April 1995 July 2000.
