چکیده
Objective: The present study is aimed at describing computed tomography findings pulmonary tuberculosis in adult AIDS patients assisted at a radiology unit of a reference infectious diseases hospital, in an attempt to establish the association between such findings and CD4 count. Materials and Methods: Forty-five patients were evaluated by chest computed tomography over a four-year period. Results: Mediastinal and/or hilar lymph node enlargement was found in 31 (68.8%) cases, pleural effusion in 29 (64.4%), centrilobular nodules with segmental distribution in 26 (57.7%), consolidation in 24 (53.3%), confluent micronodules in 17 (37.7%), poorly defined nodules with centrilobular distribution in 16 (35.5%), tree-in-bud pattern in 13 (28.9%), bronchial wall thickening in 12 (26.6%), thick-walled cavity in 10 (22.2%), miliary nodules in 9 (20%), and cylindrical bronchiectasis in 6 (13.3%). Among the 45 patients, 35 (77.8%) presented CD4 count < 200 cel/mm and 10 (22.2%) presented CD4 count ≥ 200 cel/mm. Conclusion: Differently from reports in the literature, the authors conclude that mediastinal and/or hilar lymph node enlargement and consolidation were significantly most frequent in patients with CD4 count ≥ 200 cel/mm. However, lymph nodes with hypodense center were most often observed in severely immunosuppressed patients with CD4 count < 200 cel/mm.
