  1. 浆液性囊腺瘤 • CT表现:单房,囊壁薄,厚度≤3mm，边缘光滑，囊内钙化(25%) • MRI表现:①单囊或多囊(少数)，壁薄；②囊内容物Ｔ１Ｗ极低,Ｔ２Ｗ高信号；③分隔，囊壁内少见突起（约8%）

  2. 浆液性囊腺瘤

  3. 浆液性囊腺瘤

  4. 粘液性囊腺瘤 • CT表现:单侧，多房，体积大，囊内密度高于水，囊内小囊，较少乳头状突起 • MRI表现:①单侧，多房，体积大，囊壁稍厚；②各房的信号强度可不均，信号多变,“姊妹囊”；③囊内分隔，增强扫描间隔、囊壁强化。

  5. 粘液性囊腺瘤

  6. 浆液性囊腺癌 :可双侧 ,囊性或囊实性，乳头状突起 ,可钙化(沙粒体) • 粘液性囊腺癌 :大,单侧居多,多房,囊实性,囊壁可见乳头状突起或有实质性肿块，囊液多为血性
