腹膜间皮瘤声像图特征

目的 探讨腹膜间皮瘤的声像图表现及血流信号特征.方法 分析经手术确诊病理证实的9例腹膜间皮瘤的彩色多普勒超声表现.结果 9例腹膜间皮瘤患者中,4例良性,5例恶性.声像图特征:腹膜间皮瘤表现为大量腹水伴肠粘连,腹膜常显示弥漫性或局限性增厚,典型腹膜间皮瘤为腹膜呈网状结构, 表面有多个分隔光带分成大、小不等房腔;或表现为腹腔肿块以及腹腔内液性暗区伴不规则、断续的纤维素样光带.腹膜血流不丰富.结论 腹膜间皮瘤的声像图表现无明显特异性,遇见顽固性腹水病例需提高警惕,必要时作腹膜活检或剖腹探查确诊.

Sonographic feature of peritoneal mesothelioma

Objective To approach sonographic appearance and blood flow signal characteristic of peritoneal mesothelioma.Methods Nine cases of peritoneal mesothelioma confirmed by pathology were retrospectively analyzed.Clinical appearances,and Doppler sonographic findings were studied.Results Of the 9 patients with peritoneal mesothelioma,4 cases were benign,5 cases were malignant.The classical peritoneal mesothelioma was reticular formation which had a lot of chambers in abdominal cavity.The peritoneal mesothelioma with ascites and ileus showed localized or diffused thickening of peritoneum.Or mass was seen in abdominal cavity.Sometimes it only showed ascites with lots of fibrous bands.The blood flow signal of peritoneum was not abundant.Conclusion The diagnosis of peritoneal mesothelioma by clinical appearances and sonographic feature has no specificity,so patients with obstinate ascites should be taken care.Sometimes it needs to have biopsy for diagnosis and early therapy.
