21例腹部巨大囊性病变的CT分析

Analysis of 21 Cases Abdominal Huge Cystic Lesion by CT

目的:探讨腹部巨大囊性病变的CT表现特点,提高腹部囊性病变诊断的准确性。方法:回顾性分析21例经手术病理证实的腹部巨大囊性病变的CT影像特征。结果:21例中,胰腺假性囊肿2例,肠系膜囊肿3例,卵巢囊腺瘤6例,卵巢颗粒细胞瘤1例,囊性畸胎瘤3例,卵巢内胚窦瘤1倒,库肯勃瘤1例,腹壁表皮样囊肿1例,肌间脂肪瘤伴黏液变性1例,腹腔转移性腺癌1例,黏液性囊性癌1例。结论:螺旋CT对腹部巨大囊性病变的定位、定性有独具优势的诊断价值,同时结合病变各自CT特征表现及病史,对于腹部巨大囊性病变的鉴别诊断也具重要意义。

Purpose： To explore the CT imaging characters of the abdominal huge cystic lesion, and to improve the diagnostic accuracy of cystic lesions. Methods： Twenty-one patients with operation confirmed abdominal huge cystic lesion were enrolled. And their CT characters were retrospectively analyzed. Re- suits： Of 21 cases, 2 cases were pancreatic pseudocysts, 3 were the mesenteric cysts, 6 were ovarian capsule adenomas, 1 was ovarian granulosa cell tumor, 3 were cystic teratomas, 1 was ovarian endodermal sinus tumor, 1 was krukenberg tumor, 1 was abdominal wall epidermoid cyst, 1 was mucous degeneration, 1 was celiac metastatic adenocarcinoma, and 1 was mucinous cystic carcinoma. Conclusion： Spiral CT has advantage on the localization of the abdomen huge cystic lesion. When combining disease history with the character features of the abdominal CT, huge cystic lesions could be differential diagnosed.
