Cystic neoplasms are an uncommon group among pancreatic tumors. Because of advances in noninvasive diagnostic procedures, these lesions are more frequently detected and surgically treated. New pathological entities have been recently described with their own prognosis. 1. In a large number of cases, the imaging procedures can differentiate microcystic adenoma from mucinous cystadenoma, the more frequently encountered lesions. A well-defined mass with innumerable small cysts producing a honeycomb appearance with central stellate septae is suggestive of microcystic adenoma. A well-defined multilocular mass containing thin, straight or curvilinear septae with papillary projections and local thickening is suggestive of mucinous cystadenoma. 2. No sonographic or CT finding allows the differentiation between mucinous cystadenoma and cystadenocarcinoma, however; the imaging features depend on the grade of malignancy. 3. Thus, in the majority of cases of cystic lesions, fine needle aspiration with appropriate stains is recommended.
囊性肿瘤在胰腺肿瘤中是一个不常见的类别。由于无创诊断技术的进步，这些病变被更频繁地检测到并接受手术治疗。最近已经描述了具有各自预后情况的新病理实体。1. 在大量病例中，成像检查能够区分微囊性腺瘤和黏液性囊腺瘤，后者是更常见的病变。边界清晰、有无数小囊肿、呈现蜂窝状外观且有中央星状分隔的肿块提示为微囊性腺瘤。边界清晰的多房性肿块，含有薄的、直的或曲线形分隔以及乳头状突起和局部增厚，提示为黏液性囊腺瘤。2. 然而，超声检查或CT检查结果均无法区分黏液性囊腺瘤和囊腺癌；成像特征取决于恶性程度。3. 因此，在大多数囊性病变病例中，建议进行细针穿刺并采用适当的染色方法。
