今天发了报:
胸部hrct平扫
双侧肺多发密集排列大小不一强透光囊腔,大者约数厘米,
小者仅2-3mm,其间有线状间隔,典型者间隔垂直于胸膜(胸壁)
,以中上肺胸膜下为多,另外于肺血管、支气管周围可见散在强
光区,局部密集分布。双肺未见实质性病变,未见胸腔积液,纵隔
未见明显肿大淋巴结。
意见:结合临床及影像学表现,
考虑为间隔旁型肺气肿并多发肺大泡(双侧)。
参考资料:间隔旁型肺气肿(paraseptal emphysema)

病理学表现:主要以累及远侧肺泡及其肺泡管和肺泡囊
为其特征,并特征性地以任何胸膜面和小叶间隔为界。
ct 表现:该型肺气肿的特征为由完整的小叶间隔分开
的胸膜下、支气管血管旁低衰减区,有时伴有肺大泡。
与远侧腺泡型气肿是同义词。也见于肺气肿。
pathology.—paraseptal emphysema is characterized
by predominant involvement of the distal alveoli and
their ducts and sacs. it is characteristically bounded
by any pleural surface and the interlobular septa.
ct scans.—this emphysema is characterized by
subpleural and peribronchovascular regions of low
attenuation separated by intact interlobular septa
(fig 1), sometimes associated with bullae. the
term distal acinar emphysema is synonymous.
(see also emphysema.)
