螺旋CT对脾结核的诊断价值

The Effect of multislice spiral CT on the diagnosis of splenic tuberculosis

目的探讨脾结核的螺旋CT诊断价值及其强化表现。方法结合病理分析16例脾结核患者CT表现,CT包括平扫及门静脉期增强扫描。结果16例脾结核中脾大8例。CT表现分为四型:粟粒型2例,平扫显示不清,无增强呈稍低密度;结节型8例,平扫边界模糊,环形强化4例,无强化3例,环形强化与无强化区混杂1例;脓肿型5例,平扫边界模糊,边缘蜂房样分隔强化2例,环形强化3例;纤维钙化型1例,散在点状钙化。11例伴腹部淋巴结肿大,8例呈环形强化。结论螺旋CT对于脾结核具有重要的诊断价值,一定程度上反映了脾结核的病理改变。

Objective To investigate the effect of multislice spiral CT （MSCT） in the diagnosis of splenic tuberculosis. Methods Sixteen patients with splenic tuberculosis were analyzed with MSCT, included plain and contrast-enhanced scanning in the phase of portal vein. Results There were 8 patients with splenomegaly. According to he demonstrations of MSC, there were four types including micronodular type （2 cases）, nodular type （8 cases）, apostematic type （5 cases） and calcific type （1 case）. Conclusion The MSCT could play an important role in diagnosis of splenic tuberculosis.
