为探讨胰腺囊性肿瘤的ＣＴ表现、诊断和鉴别诊断，搜集８例经手术、病理证实的胰腺囊性肿瘤，分析其ＣＴ表现。结果发现，浆液性囊腺瘤由无数直径１～２ｍｍ的低密度小囊和稍高密度间隔组成；粘液性囊腺瘤为大单囊或被分隔为几个直径大于２ｃｍ的小囊；粘液性囊腺癌为大单囊或（和）数个小子囊组成，囊壁均匀或厚薄不均，可见乳头状结节突入腔内，其中脾转移２例。作者认为：浆液性囊腺瘤绝大多数为良性肿瘤，具有较典型的ＣＴ表现，术前诊断对病人的治疗和预后有重要意义。粘液性囊腺瘤和囊腺癌是病变发展的不同阶段，前者偏良性，但极易转变为恶性的囊腺癌，手术切除是两者最理想的治疗方法。
In order to investigate CT findings, diagnosis and differential diagnosis of pancreatic cystic tumors, 8 cases of pancreatic cystic tumors confirmed by surgery and pathology were collected and their CT findings were analyzed. The results showed that the serous cystadenoma by a small number of 1 ~ 2mm in diameter and a small density of small densely spaced intervals; mucinous cystadenoma large single capsule or divided into several small diameter of more than 2cm; mucus Cystadenocarcinoma is a large single capsule or (and) several ascus, wall uniform or uneven thickness, visible papillary nodules into the cavity, of which 2 cases of splenic metastasis. The authors believe that: the vast majority of serous cystadenomas are benign tumors, with more typical CT findings, preoperative diagnosis of patients with treatment and prognosis of great significance. Mucinous cystadenoma and cystadenocarcinoma are different stages of the development of the lesion, the former is benign, but easily transformed into malignant cystadenocarcinoma, surgical resection is the best treatment for both.
