目的　分析腹膜间皮瘤的超声声像图特征 ,探讨超声对腹膜间皮瘤的诊断价值。方法　对 2 3例腹膜间皮瘤的超声声像图及其中 9例的彩色多普勒检查结果进行分析和总结 ,并将其声像图表现与手术及病理诊断相对照。结果　腹膜间皮瘤的超声声像图表现为 :1 8例探及腹腔或盆腔肿块 ,回声不均匀 ,部分肿块内可见不规则暗区 ;腹膜弥漫性层状或结节状增厚 1 1例 (其中 6例合并腹腔肿块 ) ,腹水 1 7例。彩色多普勒显像示肿块内较丰富的血流信号。结论　超声检查结合临床对本病可做出初步诊断 Objective To analyze the ultrasonographic features of peritoneal mesothelioma and to evaluate the diagnostic value of ultrasound in peritoneal mesothelioma. Methods Twenty-three cases of peritoneal mesothelioma by ultrasonography and nine cases of color Doppler examination results were analyzed and summarized, and its sonographic findings and surgical and pathological diagnosis of the control. Results Peritoneal mesothelioma ultrasonography showed: 18 cases of exploration and abdominal or pelvic mass, the echo is not uniform, some of the mass visible irregular dark areas; peritoneal diffuse lamellar or nodular thickening 11 cases (Including 6 cases of abdominal mass), ascites 17 cases. Color Doppler imaging showed relatively abundant blood flow within the tumor. Conclusion Ultrasound combined with clinical diagnosis of the disease can make a preliminary diagnosis
