Comparative study between CT findings of pulmonary tuberculosis in immunocompromised and immuned normal patients

Objective To evaluate the CT features of pulmonary tuberculosis between immunocompromised patients compared with immuned normal patients. Methods The complete data, including chest CT scanning and laboratory results of 213 patients with pulmonary tuberculosis from 2006 to 2009 were retrospectively studied. The patients were classified as immunocompromised group （18 cases） and immuned normal group （195 cases） and the CT features of these two groups were compared. Results CT features of tuberculosis in immunocompromised group included larger confluent consolidation（77.78%）, multiple small cavities within any given lesion （66.67%）, nodular opacities （38.39%）, tree-in-bud （50.0%）, pleural effusion （61.11%） and enlarged mediastinal lymph nodes （55.56%）. CT findings of tuberculosis in immuned normal group included larger confluent consolidation （24.62%）, multiple small cavities within any given lesion （9.23%）, nodular opacities （42.05%）, tree-in-bud （45.64%）, pleural effusion （50.26%） and enlarged mediastinal lymph nodes （29.78%）. There were significantly differences （P〈 0.05） in the findings of larger confluent consolidation,multiple small cavities within any given lesion,and enlarged mediastinal lymph nodes, without any significantly differences （P 〉 0.05）in the findings of nodular opacities,tree-in-bud, pleural effusion. Conclusion Immunocompromised patients have a higher prevalence of larger confluent consolidation, multiple small cavities within a given lesion and enlarged mediastinal lymph nodes than immuned normal patients.
