摘　　要：目的探讨超声对腹膜假黏液瘤(PMP)的诊断价值,总结其声像图特点,并与CT结果对照。方法回顾分析经本院手术病理证实的25例PMP的术前超声及CT检查资料。结果 25例患者超声提示腹膜假黏液瘤3例,CT提示6例,两者诊断符合率差异无统计学意义(P=0.579)。PMP的超声特征性声像图表现为:腹腔积液内见密集点状回声或絮状物,随体位不移动或移动性差;病变呈蜂窝样;胶冻样黏液和/或黏液性病变在肝脾表面形成压迹。结论目前超声与CT对PMP诊断率均低;PMP有特异性声像图表现,大多数病例术前超声诊断是可能的。Objective To investigate the value of ultrasound in the diagnosis of pseudomyxoma peritonei（ PMP） and summarize the ultrasonographic features of PMP by comparing with computed tomography（ CT）findings. Method Ultrasound and CT scan results of 25 patients with PMP confirmed by pathology after surgery were analyzed retrospectively. Results Among these 25 PMP patients,three were diagnosed by ultrasound and six by CT（ P = 0. 579）. The specific ultrasonographic features of PMP were as follows： the dense punctuate echoes or floccules were detected in hydrops abdominis,which seldom or never move with the change of body position. Honeycomb-like lesions were typical. Notches were formed on the surface of liver or spleen due to the mucinous material and / or the mucinous lesions. Conclusions Both ultrasound and CT scan have poor detection rate in the diagnosis of PMP. PMP has specific ultrasonographic features,which may make it possible to diagnose most PMP lesions by ultrasound before surgery.
