Abstract: Objective To evaluate X-ray and CT features Of pulmonary tuberculosis in diabetic patients,patients with dropsical nephritis,patients with systemic lupus erythematosus(SLE),and patients with acquired immunodeficiency syndrome(AIDS).Method Retrospective analysis were done on CT scans and X-ray features Of pulmonary tuberculosis cases combined with 68 with diabetiC(68),with dropsical nephritis(20),with SLE(12),with AIDS(8).Results X-ray and CT features of pulmonary tuberculosis combined With diabetic included larger infiltrate consolidation(45 cases),multiple cavities with infiltrate consolidation(40 cases),nosegmental distribution(23 cases),bronchi disseminate focus(21 caseS),and pleural fluid(10 cases).The X-ray and CT appearances of pulmonary tuberculosis patients combined with dropsical nephritis or SLE inclUded acute hematogenous dissemination pulmonary tuberculosis(15 cases),vary sized infiltrate consolidation(17 cases),complicating lymphadenectasis in hilum of lung and mediastinum(4 cases).The CT findings of pulmonary tuberculosis combined with AIDS were patch shadow complicated With lymphadenectasis(5 cases),and acute hematogenous dissemination pulmonaryary tuberculosis complicated with lymphadenectasis(3 cases) Conclusion The main radiological findings of pulmonary tuberculosis in immune hypofunction patients appear larger infiltrate consolidation,multiple cavities within infiltrate consolidation,bronchi disseminate,acute hematogenous dissemination pulmonary tuberculosis,lymphadenectasis in hilum of lung and mediastinum,and infiltrate tuberculosis consolidation in uncommon parts.
