目的 　探討自身免疫性胰腺炎（AIP）的CT表現(xiàn)特征。
方法 　收集4例經(jīng)臨床、實驗室檢查和類固醇激素治療有效的AIP患者的CT 資料。CT檢查包括平掃、雙期（動脈期和門靜脈期）增強掃描,在CT圖像上觀察胰腺的形態(tài)、大小、質(zhì)地、強化程度、胰管、胰腺邊緣、胰周及腹膜后各間隙等情況并分析AIP的CT表現(xiàn)特征。
結(jié)果 　3例AIP表現(xiàn)為胰腺彌漫性腫大，1例為胰頭的局限性腫大； 病變區(qū)域胰腺實質(zhì)在動脈期強化減弱但出現(xiàn)明顯的延時強化； 2例在胰腺病變區(qū)周圍環(huán)繞包膜樣結(jié)構(gòu)； 2例伴膽總管胰頭段狹窄，1例ERCP顯示胰管不規(guī)則狹窄； 經(jīng)類固醇激素治療后，CT復查顯示胰腺情況明顯好轉(zhuǎn)。
結(jié)論 　AIP的CT表現(xiàn)具有一定的特征性。
