肺结核厚壁空洞的多层螺旋CT诊断

目的探讨肺结核厚壁空洞的多层螺旋CT诊断。方法回顾性分析35例病理证实的肺结核厚壁空洞。全部病例均进行了多层螺旋CT(MSCT)平扫及增强扫描。结果34例厚壁空洞周围均存在不同程度的卫星病灶,32例可见空洞以外其他肺叶及肺段的结核病灶,31例厚壁空洞位于上叶尖后段及下叶背段,30例为类圆形,7例空洞壁可见钙化灶,3例可见壁结节,2例可见液平,所有病例均未见胸膜凹陷征。结论MSCT能清晰显示肺结核厚壁空洞、卫星灶及空洞以外结核病灶的特点,是肺结核厚壁空洞最有效的诊断方法。

Multislice CT diagnosis of thick wall cavities of pulmonary tuberculosis

Objective To study multislice CT (MSCT) diagnosis of the thick wall cavities of pulmonary tuberculosis. Methods Thirty-five patients with thick wall cavities of pulmonary tuberculosis confirmed by pathology were analyzed retrospectively. All patients underwent MSCT with and without enhancement. Results Satellitic lesions were seen in 34 cases. The tuberculous lesions except the thick wall cavities were found in the other lobes and segments of lungs in 32 cases.Thirty-one were located at the superior lobe and dorsal segment of lower lobe. Thirty of the cavities were round or similar round. Calcification was shown in the thick wall of 7 cases. Three cases were revealed mural nodules and fluid level was found in 2 cases. No pleural indentation was demonstrated in all cases. Conclusion MSCT can clearly display the thick wall cavities, satellitic lesions and the other tuberculous lesions. And it is the most effective method of diagnosing thick wall cavities of pulmonary tuberculosis.
