弥漫性恶性腹膜间皮瘤超声与病理分析

目的再探讨超声对恶性腹膜间皮瘤的诊断要点。方法总结分析15例超声引导下介入活检病理诊断为恶性腹膜间皮瘤的超声资料。结果15例间皮瘤壁层腹膜厚薄不均，边界不整齐；腹膜线连续性中断，肿块部位回声低；网膜呈饼状不均性增厚，质硬感，边缘不整齐；超声引导下活检易取材，质硬，网膜不随针的提插而移动；CDFI：肿块内血流较丰富，11例RI〈0．60，4例RI〉0．60；病理：12例为上皮型，3例为腺管乳头型。结论弥漫性恶性腹膜间皮瘤有一定的超声特点，结合超声引导下活检能基本做出对该病的诊断与鉴别诊断。

The Contrasted Analysis in Diffuse Malignant Peritoneal Mesothelioma Thru Ultrasonography and Pathology

Objective To evaluate the diagnostitic major points of ultrasound in diffuse malignant peritoneal mesothelioma.Methods Fifteen cases with diffuse malignant peritoneal mesothelioma were diagnosed and analysed by pathological biopsy under the guidance of ultrasound.Results Images of 15 cases showed that both the thickness of the walls of peritoneal mesothelioneal and its fringe were irregular,the peritoneal boundary was not defined and discountinued.The echo from the mass was hypo-active.The omentum was thickened and hard like placenta,and its fringe irregular.Biopsy under the guidance of ultrasound was performed easy.The omentos were hard didn't shift when the needle moved.CDFI:Inside the mass,the blood flow was rich.11 cases RI<0.60;4 cases RI>0.60.pathology:12 cases were epithelium and 3 cases were papillary tubular adenoid.Conclusions Diffuse malignant peritoneal mesothelioma,having the characteristic of ultrasonic image,can be grossly diagnosed in combination with the biopsy under the guidance of ultrasound.
