目的 :研究脾结核的CT诊断。方法 :回顾性分析经手术病理证实或经抗结核治疗治愈而确诊的 15例脾结核的CT表现。结果 :15例中 14例脾脏增大 ,11例平扫表现为多发大小不等的结节状或斑点状低密度灶 ,边界清或欠清 ,增强后病灶内部不强化 ,边缘变清楚 ;1例除脾内多发状低密度灶外 ,还可见多发小结节状钙化灶 ;2例为散在小点状钙化灶。 10例伴有其他脏器结核 ,9例伴后腹膜、肝脾门区等淋巴结肿大或钙化。 7例淋巴结呈环状强化。结论 :脾脏多发大小不等的结节状或斑点状、低密度、无强化病灶是脾结核的主要征象 ,CT为发现脾结核较好的检查方法 Objective: To study CT diagnosis of splenic tuberculosis. Methods: The CT findings of 15 cases of splenic tuberculosis confirmed by surgery and pathology or cured by anti-TB therapy were retrospectively analyzed. Results: The spleen of 14 cases increased in 15 cases. The nodules or spot-like low-density lesions showed in 11 cases with clear-cut or clear border. The border of the lesion was not enhanced and the margin became clear after enhancement. In addition to multiple spleen intradural low density lesions, but also showed multiple small nodular calcification; 2 cases scattered scattered dot calcification. 10 cases accompanied by other organs tuberculosis, 9 cases with retroperitoneal, hepatosplenomegaly and other lymph nodes or calcification. Seven cases of lymph nodes were ring-shaped enhancement. Conclusions: Nodules or spots with splenomegaly multiple sizes, low density and no intensive lesions are the main signs of splenic tuberculosis. CT is a better method to detect splenic tuberculosis
