胰腺黏液性囊性肿瘤和浆液性囊腺瘤的多层CT对比研究

Multi-slice computed tomography for diagnosis of mucinous cystic neoplasms and serous cystadenomas of the pancreas

探讨多层CT在胰腺黏液性囊性肿瘤和浆液性囊性腺瘤诊断和鉴别诊断中的价值。方法 回顾性分析于2003年5月至2009年12月在我院经手术病理证实的黏液性囊性肿瘤患者（19例）和胰腺浆液性囊腺瘤（13例）的多层CT图像。图像分析包括肿瘤位置、形态、囊腔直径、囊壁、分隔、钙化、实性成份、胰腺萎缩、主胰管扩张、边界情况等。结果 胰腺黏液性囊性肿瘤与胰腺浆液性囊腺瘤囊腔直径大小比较有统计学意义（P=0.009）；囊腔直径大于2 cm多见于黏液性囊性肿瘤，与浆液性囊腺瘤之间差异统计学意义（P=0.01）；肿瘤实性成分多见于浆液性囊腺瘤，与粘液性囊性肿瘤比较有统计学意义（P=0.029）。结论 多层 CT在胰腺黏液性囊性肿瘤和浆液性囊性腺瘤诊断和鉴别诊断中具有重要的临床价值。

Objective To assess the value of multi-slice computed tomography（MSCT） in the diagnosis and differential diagnosis of pancreatic mucinous cystic neoplasms and serous cystadenoma.Method The MSCT images were reviewed for 19 pathologically confirmed cases of pancreatic mucinous cystadenomas and 13 cases of pancreatic serous cystadenomas（n=13） treated in our center between July,2003 and December,2009.The CT features were analyzed including the tumor location,contour,dimension of the largest cyst,cystic wall,septation,presence of calcification,solid component,pancreatic atrophy,main pancreatic duct dilatation,and lesion margins.Results Significant differences were found between the two groups in lesion diameter（P=0.009）,cyst distribution of the largest cyst（2 cm）（P=0.01）,and the presence of solid component（P=0.02）.Conclusion MSCT can be of important value in the diagnosis and differential diagnosis of pancreatic mucinous cystic neoplasms and serous cystadenomas.
