胰腺浆液性囊腺瘤的超声诊断价值

Diagnosis of pancreatic serous cystadenomas with ultrasonography

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 assess the value of ultrasonography （US） in the diagnosis of pancreatic serous cystadenomas. Methods From Jan. 2000 to May.2008 in our hospital, thirty-six patients with pancreatic serous cystadenoma confirmed by surgery and pathology were retrospectively reviewed. Results There were 37 pancreatic serous cystadenomas in 36 patients, among which 34 tumors were detected by US. Three tumors were missed on US and the detection rate was 91.9%（34/37）. Four tumors were mislocated and the accuracy of locating the serous eystadenomas by US was 81.1%（30/37）. Cystic-solid masses, cystic masses, or solid echogenic masses were found in the pancreas in 17 cases, 8 cases and 9 cases, respectively. The aceuraey of diagnosing the nature of the cystic pancreatic lesions was 82.4%（28/34）by US, but Only 8 cases were correctly diagnosed as serous cystadenomas. Conclusion US features of typital serous cystadenomas are honeycombed appearance with numerous cysts. Definitive diagnosis is often possible when the lesion has a typical US appearance. On the contrary, different kinds of imaging modalities can be helpful in differentiating diagnosis of cystic neoplasms of the pancreas.
