Abstract:
Objective To investigate the spiral CT findings in hemopathic patients with druginduced pulmonary injury.Methods CT images obtained in 11patients with drug-induced pulmonary injury were retrospectively analyzed.Six patients had antineoplastic agent-induced pulmonary injury and 5 patients had non-neoplastic agent-induced pulmonary injury (immunosuppressor in 2 patients,antifungal in 2 patients,antineoplastic immunomodulators in 1 patient).CT findings were reviewed by a chest radiologist.Results All 11patients had parenchymal abnormalities on MSCT scans,including ground-glass opacities( n =8 ),consolidation( n =5 ),interlobular septal thickening( n =3 ) and focal fibrosis ( n =2 ).The abnormalities were bilateral and asymmetric in all patients.They were mainly in the peripheral lung regions in 6 patients,in the central lung regions in four,and irregularly located in one.The abnormalities involved mainly the lower lung zones in six patients,the upper lung zones in two,and all lung zones homogeneously in three.One patient had fluid in bilateral pleural cavities.Three patients were given the same agent once more after the imaging turned to normal,and they presented with same clinical symptoms and similar but more serious imaging findings.Conclusions Drug-induced pulmonary injury usually manifests as areas of ground-glass opacity and consolidation,which most commonly involves the peripheral lungs and lower lung zones.Drug-induced pulmonary injury shows reproducible but more serious lesions when the patient is given the same agent once more.
