RESUMO
Objective To study the chest image appearances of penicilliosis marneffei(PSM)in patients with acquired immune deficiency syndrome(AIDS).Methods Chest imaging features of PSM in 36 patients with AIDS were retrospectively analyzed.Results Radiographic features of infiltrative lesions and focal lung consolidation were found in 14 cases(38.89%),in which 2 cases were with single lung disease(5.56%)and 12 cases with bilateral lung involvement(33.33%).Eight cases had diffuse lesions (22.22%),10 cases had reticular image patterns(27.78%),9 cases had nodular patterns(25.00%), 7 cases had ground-glass shadows(19.44%),6 cases had diffuse miliary lesions(16.67%),4 cases had enlarged bilar and enlarged mediastinum lymph nodes(11.11%).Cystic lesions was found in 5 cases (13.89%).Four cases had pleural effusion(11.11%),and 2 cases had nodular bump(5.56%). Pericardial effusion and pneumothorax each appeared in 1 case(2.78%).By HRCT,infiltrative lesion and focal lung consolidation were found in 32 patients(88.89%),in which 4 cases were with single lung lesions (11.11%)and 28 cases were with bilateral lung lesions(77.78%).Thirteen cases had diffuse lesions (36.11%),10 cases had pulmonary interstitial hyperplasia(27.78%),9 cases had nodular patterns (25.00%),8 cases had ground-glass shadows(22.22%),9 cases had diffuse miliary lesions(25.00%), 21 cases had enlarged lymph nodes in the mediastinum(58.33%).Cystic lesions were found in 8 cases (22.22%).Thirteen cases had pleural effusion(36.11%),and 2 cases had nodular bump(5.56%). Pericardial effusion and pneumothorax each appeared in 1 case(2.78%).Conclusion The image appearances of PSM in patients with AIDS include infiltrative lesions or focal lung consolidation,ground- glass shadow,enlarged hilar and mediastinum lymph nodes,pleural effusion,interstitial involvement or reticular image pattern(pulmonary interstitial hyperplasia),diffuse miliary lesion,and cystic lesion.
