摘    要:目的 探讨胰腺结核及胰周淋巴结结核的影像学表现及诊断要点,评价影像学检查对其的诊断价值.方法 选取胰腺结核和胰周淋巴结结核患者5例,2例为手术病理学证实,3例为经抗结核治疗追踪临床证实;其中2例为胰头部结核伴胰周淋巴结结核,3例为胰头周围淋巴结结核(伴脾脏结核1例).5例均行多层螺旋CT(MSCT)平扫+三期动态增强扫描,其中1例行MRI平扫,1例行MRI平扫+三期动态增强扫描.回顾性分析患者的MSCT和MRI表现.结果 2例胰头部结核伴胰周淋巴结核,1例伴钙化,CT表现为多发结节状混杂密度灶,轻度-中度蜂窝样强化,并伴有胰周淋巴结肿大,部分融合,呈环形强化.3例胰头周围淋巴结结核CT表现为淋巴结肿大,向上延伸至肝门部,部分融合,1例合并脾脏粟粒样结核灶,增强扫描显示肿大淋巴结呈环状强化.2例胰头周围淋巴结结核MRI表现T1WI为等或略低信号,T2WI为稍高信号,扩散加权成像(DWI)呈高信号,增强扫描显示边缘环形强化.结论 胰腺结核和胰周淋巴结结核的CT表现为胰腺局灶蜂窝状轻中度强化,肿块及胰周淋巴结肿大伴边缘环状强化,可合并脾脏等腹腔结核灶,影像学表现有一定的特异性.
