摘要 目的探讨CT值在胰腺炎性假性囊肿与黏液性囊性肿瘤(MCN)、导管内乳头状黏液性肿瘤(IPMN)鉴别诊断中的价值。方法选择行多排螺旋CT(MDCT)检查并经手术病理证实为炎性假性囊肿和MCN、IPMN的患者,在图像分析和传输系统工作站中测量每个病灶的CT值并比较其差异。结果共48例胰腺单房囊肿患者被纳入研究,包括31例炎性假性囊肿、10例MCN和7例IPMN。所有病灶的最大径为(3.49±1.71)cm,其中炎性假性囊肿为(3.56±1.98)cm,MCN为(3.34±0.96)cm,IPMN为(3.37±1.08)cm,差异无统计学意义(F=0.080,P:0.924)。炎性假性囊肿的CT值为(22.44±7.90)HU,明显高于MCN的(13.16±6.57)HU与IPMN的(12.29±3.86)HU,差异均有统计学意义(P=0.001);而MCN与IPMN的CT值差异无统计学意义(P=0.451)。所有凳陛假性囊肿、MCN、IPMN的CT值与病灶直径之间无相关性(P〉0.05)。结论胰腺单房囊肿中炎性假性囊肿的CT值比MCN高,临界CT值14.0HU有助于鉴别炎性假性囊肿与MCN。
