多层螺旋CT对胰腺囊性肿瘤的诊断价值

The diagnostic value of multislice CT in cystic neoplasms of the pancreas

目的探讨多层螺旋CT对胰腺囊性肿瘤的表现和诊断价值,以提高对该类疾病的认识。方法回顾性分析谷城县人民医院2010年1月-2013年1月18例经手术或穿刺活检标本病理证实的胰腺囊性肿瘤患者的CT资料。结果浆液性囊腺瘤8例,7例小囊型,1例大囊型,小囊型病灶较小,囊内有分隔,强化是呈海绵状,1例可见中央星状瘢痕伴钙化,大囊型病灶呈薄壁大囊,无囊壁结节及分隔,增强扫描囊壁轻度强化;黏液性腺瘤6例,2例表现为单房囊性病灶,4例表现为多房分隔囊性病灶,增强后壁有强化;黏液性囊腺癌2例,1例伴有肝转移;实性假乳头状瘤2例,均为囊实混合型。结论多层螺旋CT对胰腺囊性肿瘤具有高度敏感性,不同病变有其特征表现,对术前诊断有一定价值。

Objective To explore the imaging features and diagnostic value of cystic neoplasms of the pancreas with muhislice CT （MSCT） , and further acknowledge these diseases. Methods MSCT data of 18 patients confirmed by surgery and pathology in the Gueheng County People＇ s Hospital from Jan. 2010 to Jan. 2013 were retrospectively analyzed. Results Eight cases were serous cystadenoma, among them, 7 cases showed ＂ microeystic type＂, with typical image manifestations which were composed of grape-like collections of predominantly small （ 〈 2 em） , with characteris- tic central scar and without mural nodule. ＂maerocystie type＂ was shown in 1 case, with large thin-walled single cystic lesions and without center scar. 6 cases were mucinous cystadenoma, among them, 4 cases manifested multi-cells with large cystic lesions, and 2 cases showed uniloeular. 2 cases of mucinouadenocareinomas showed large capsule multi-cells with thick capsule and mural nodules, and one of them showed liver metastases. 2 cases of pancreatic intraduetal papillary neoplasms showed multiple lesions with thick and rough septa and solid-cystic. Conclusion CT has a high degree sensitivity of different lesions in the diagnosis of pancreatic eytie neoplasms, with certain characteristics and value for preoperative diagnosis.
