“肺大疱”和“肺大泡”的区别

时间: 2017-12-18 【打印页面】 【关闭窗口

  在我们报告中常常会出现“肺大疱”或者“肺大泡”的字样,到底是哪个正确的呢?这里需要指出是应该用“肺大疱”这一专业术语。肺大疱的英文称为“bulla”,我们先看看Fleischner Society是如何解释的。

  bulla(肺大疱)

  Pathology:An airspace measuring more than 1 cm - usually several centimeters - in diameter, sharply demarcatedby a thin wall that is no greater than 1 mm in thickness. A bulla is usually accompanied by emphysematous changes in the adjacent lung.

病理:大于1cm且与周围分界清晰的薄壁腔隙(通常为数厘米),壁<1mm,通常肺大疱临近周围伴随肺气肿改变。

  Radiographs and CT scans:A bulla appears as a rounded focal lucency or area of decreased attenuation, 1 cm or more in diameter, bounded by a thin wall (Fig 16). Multiple bullae are often present and are associated with other signs of pulmonary emphysema (centrilobular and paraseptal).

平片与CT扫描: 肺大疱表现为直径≥1cm的局灶性圆形透亮影或密度减低区,以薄壁为界。多发肺大疱很常见,并常伴有肺气肿征象(小叶中央型肺气肿、间隔旁型肺气肿)

  该不该用“肺疱”这个词?

  bleb(疱)

  Anatomy:A bleb is a small gas-containing space within the visceral pleura or in the subpleural lung, not larger than1 cm in diameter.

解剖:“疱”是指在脏层胸膜内或在胸膜下肺内的小含气腔隙,直径小于1cm。

  CT scans:A bleb appears as a thin-walled cystic air space contiguous with the pleura. Because the arbitrary (size) distinction between a bleb and bulla is of little clinical importance, the use of this term by radiologists is discouraged.

  CT扫描:与胸膜相邻的薄壁囊状含气腔隙。由于疱与大疱的大小界定没有太多的临床意义,因此不推荐影像科医生使用疱(bleb)这个词。
