摘　　要：目的探讨腹膜腔囊性病灶的CT诊断及应用价值。方法对照分析20例腹膜腔囊性病灶的CT表现和手术、病理结果。结果3例腹膜腔单纯性浆液或黏液性的囊肿,CT均表现为边界清晰的囊性包块,4例囊腺瘤或囊腺癌可见增厚的囊壁和结节,3例肠系膜上的囊性肿瘤呈蔓藤飘浮状。3例腹膜腔假性黏液瘤在肝脏前、后间隙和结肠下间隙见多个有分隔状囊性肿块。2例腹膜腔囊性间皮瘤局限于下腹腔,壁稍厚,有强化。5例腹膜腔血肿均有外伤史,表现为上腹部器管间隙内边缘清晰的囊性包块。结论CT能清晰地显示腹膜腔囊性病灶的部位、形态、范围,对临床诊断和治疗有重要价值。Objective To study the CT features of peritoneal cystic lesions. Methods CT findings of 20 cases with peritoneal cystic lesions were analyzed and compared with the operative and pathological results. Results According to the CT findings, 3 cases of serous or mucous cyst were found to be well-defined cystic masses. 4 cases of cystadenaoma or cystadenocarcinoma showed thickened cyst wall with nodules. 3 cases of mesenteric cystic tumor were depicted as bine-like lesions. In 3 cases of pseudomyxoma peritoneal, multiple cystic masses with septations were located in anterohepatic, posthepatic and subcolonic space respectively. 2 cases of cystic mesothelioma were confined to lower abdominal cavity and enhancement was observed within cyst wall, which was slightly thickened. 5 cases of abdominal hematoma, of which all patients had the history of injury, were revealed as well-defined cystic masses located within inter-visceral space in upper abdominal cavity. Conclusion CT can provide the informations of the position, shape and range of peritoneal cystic lesions, and has high clinical value in diagnosis and treatment.
