【摘要】 目的 进一步认识空洞型肺结核的X线与CT的诊断价值。 方法 回顾性分析38例空洞型肺结核的X线、CT影像表现，其中16例痰菌阳性证实，13例经支纤镜检查证实，9例经临床证实。 结果 38例中共有55个大小不等空洞，其中X线平片显示26个空洞，空洞大小为6～43mm，CT显示55个，空洞大小为2～43mm。空洞型肺结核的好发部位为两肺上叶尖后段及下叶背段。X线平片显示空洞周围卫星病灶23例，CT显示35例。X线显示空洞引起肺内支气管播散6例，CT显示12例。X线显示结核空洞外侧胸膜增厚3例，CT显示11例。CT显示纵隔内及肺门旁淋巴结肿大3例。 结论 CT在显示空洞的位置、数目、大小、形态、洞壁厚薄、洞内外细节及结核沿支气管播散等方面优于X线平片。X线平片拟诊肺结核的患者宜行CT做进一步检查。
