目的探讨胰腺浆液性囊腺瘤的超声表现与诊断。方法对2000年1月至2008年5月中山医院外科手术病理证实的36例胰腺浆液性囊腺瘤的超声表现进行回顾性分析。结果36例37个病灶,超声显示34个,检出率91.9%(34/37),其中4个超声定位错误,定位诊断符合率81.1%(30/37)。超声表现囊实性17例,囊性8例,实性9例;超声诊断良性病变28例,良恶性诊断符合率82.4%(28/34),但仅8例诊断正确,诊断正确率仅23.5%。结论胰腺浆液性囊腺瘤的典型超声声像图表现是由无数个小囊组成的多房囊性病灶,根据典型声像图可作出正确诊断,表现不典型时需结合其他影像学检查。
Objective To investigate the ultrasound findings and diagnosis of pancreatic serous cystadenoma. Methods A retrospective analysis was performed on the ultrasound findings of 36 cases of pancreatic serous cystadenoma confirmed by surgical operation of Zhongshan Hospital from January 2000 to May 2008. Results Thirty-six lesions were observed in 36 lesions and 34 lesions were detected by ultrasonography. The detection rate was 91.9% (34/37). Four of them were mis-located and the coincidence rate was 81.1% (30/37). Ultrasound showed cystic solidity in 17 cases, cystic in 8 cases, solid in 9 cases; ultrasonography in 28 cases of benign lesions, benign and malignant diagnostic coincidence rate of 82.4% (28/34), but only 8 cases were diagnosed correctly, the diagnostic accuracy was only 23.5 %. Conclusions The typical ultrasonography of pancreatic serous cystadenoma is a multicellular cystic lesion composed of innumerable small vesicles. Correct diagnosis can be made according to the typical sonogram, and other radiological findings should be combined with atypical pancreatic cystadenoma.
