纵隔的分区在判断纵隔肿块的来源和性质上有重要意义。

纵隔分区

纵隔位于两肺之间，上界胸廓入口，下界横膈，前界胸骨，后界胸椎。它包含心脏、大血管、气管、主支气管、食管、胸腺、淋巴组织、神经及脂肪等和组织。除气管及支气管可以分辩外，其余结构间无明显对比，只能观察其与肺部邻接的轮廓。

纵隔的分区在判断纵隔肿块的来源和性质上有重要意义。纵隔的分区有几种，我们采用九分区法，即在侧位胸片上，将纵隔按纵的和横的方向划两条线，各分为三个部分共计分为九个区。纵的方向分区：

前纵隔：系胸骨后缘与气管、升主动脉和心脏前缘的间隙，为较透光的倒置狭长的三角形，其中主要有胸腺和前纵隔淋巴结；
中纵隔：相当于心脏、主动脉弓、气管和肺门所占据的范围；
后纵隔：食管前缘以后内含食管，降主动脉，胸导管、静脉、交感神经及淋巴结等。

横的方向划为自胸骨柄、体交界入至第四胸椎体下缘划水平线，其上为上纵隔，该线以下至肺门下缘水平线之间为中纵隔，其下方至横膈之间为下纵隔。
