摘　　要：目的总结腹膜假性粘液瘤的CT表现特点,提高对本病的诊断水平。方法选取经手术及病理证实的腹膜假性粘液瘤10例,术前均行腹部CT平扫和增强扫描,回顾分析其CT影像表现。结果10例出现腹盆腔脏器扇贝样压迹;9例表现为腹腔、盆腔脏器周边的分房粘液团块,可单发或多发,囊内密度均匀,CT值略高于水,增强后边缘强化;5例显现原发肿块,6例有腹膜后淋巴结肿大,7例合并有网膜、肠系膜浸润,出现网膜饼状改变,5例有腹水;3例合并钙化。结论腹膜假性粘液瘤的影像学表现具有一定的特征性,充分认识其CT征象,有利于作出正确的诊断。Objective To study the CT display of pseudomyxoma peritonei, and raise the level of diagnosis and differential diagnosis of the disease. Methods 10 cases of pseudomyxoma peritonei had proceeded with plain and contrast enhancement CT check before operation.
