Successful ultrasonic detection and fine needle aspiration of pleural effusions, loculated fluid, and peripheral lung masses were done in 115 patients. No complications, eg, pneumothorax or hematoma, were caused by the fine needle aspirations. There was no false-negative or false-positive cytology because of excellent localization by ultrasound and adequate tissue samples. This series shows ultrasonography to be a valid method of evaluating chest lesions seen to be peripheral on chest roentgenograms. The cystic or solid nature of these lesions was determined; however, we experienced difficulty in differentiating small amounts of loculated fluid from pleural thickening in a few cases. Difficulties were also noted with a few small peripheral tumors that appeared to be cystic on ultrasonography but were proven to be solid by fine needle aspiration. These problems can be resolved by an experienced sonographer using equipment with higher resolution, but we did not hesitate to do fine needle aspiration in such circumstances.
对115例患者成功进行了胸腔积液、局限性液体及周围型肺肿块的超声检测和细针穿刺抽吸。细针穿刺抽吸未引起任何并发症，如气胸或血肿。由于超声定位准确且组织样本充足，未出现假阴性或假阳性细胞学结果。本系列研究表明，超声检查是评估胸部X线片上显示为外周性的胸部病变的有效方法。确定了这些病变的囊性或实性性质；然而，在少数情况下，我们难以区分少量局限性液体与胸膜增厚。对于一些在超声检查中看似囊性但经细针穿刺抽吸证实为实性的小外周肿瘤，也存在困难。经验丰富的超声检查人员使用分辨率更高的设备可以解决这些问题，但在这种情况下我们仍毫不犹豫地进行细针穿刺抽吸。
