目的：探討少見(jiàn)縱隔占位病變的螺旋CT表現(xiàn)特征及其病理基礎(chǔ)，以提高臨床認(rèn)識(shí)及診治水平。方法：回顧性分析經(jīng)臨床病理證實(shí)的原發(fā)性少見(jiàn)縱隔占位病變的螺旋CT表現(xiàn)，觀察和評(píng)價(jià)腫塊內(nèi)部結(jié)構(gòu)、密度分布、邊緣特征、強(qiáng)化特征等CT表現(xiàn)特點(diǎn)及其優(yōu)勢(shì)解剖分布。結(jié)果：32例少見(jiàn)縱隔腫塊中良性22例（68.75％，22/32），惡性10例（10/32，31.25％）。22例良性腫塊中密度均勻12例（12/22，5454％），形態(tài)規(guī)則16例（16/22，72.72％），邊界清楚14例（14/22，63.64％），低密度15例（15/22，68.18％）。10例惡性腫塊中密度不均勻7例（7/10，70％），形態(tài)不規(guī)則8例（8/10，80％），邊界不清楚6例（6/10，60％），中等密度6例（6/10，60％）。32例腫塊中位于上縱隔12例，前縱隔16例，中縱隔9例，后縱隔11例。良性腫塊常累及一個(gè)解剖分區(qū)（15/22,68.18％），惡性多累及二個(gè)區(qū)以上（6/10,60％）。結(jié)論：不同的少見(jiàn)縱隔腫塊具有不同特征CT表現(xiàn)及其好發(fā)部位，這與其解剖來(lái)源和其組織成分不同有關(guān)
