Differentiation of pulmonary complications with extensive ground-glass attenuation on high-resolution CT in immunocompromised patients

Purpose The purpose of this study was to compare the high-resolution CT (HRCT) findings of pulmonary infectious and noninfectious complications with extensive ground-glass attenuation (GGA) in immunocompromised patients. Materials and methods One hundred fifty-two immunocompromised patients with pul...

Description
Summary:Purpose The purpose of this study was to compare the high-resolution CT (HRCT) findings of pulmonary infectious and noninfectious complications with extensive ground-glass attenuation (GGA) in immunocompromised patients. Materials and methods One hundred fifty-two immunocompromised patients with pulmonary complications that showed extensive GGA (> 50% of the whole lung on HRCT) were included in this study. The diagnoses of the 152 patients were as follows: pneumocystis pneumonia (PCP), n  = 82; drug-induced pneumonia, n  = 38; bacterial pneumonia, n  = 9; cytomegalovirus pneumonia, n  = 6; idiopathic pneumonia syndrome, n  = 6; diffuse alveolar hemorrhage (DAH), n  = 4; fungal infection, n  = 3; tuberculosis, n  = 2 and pulmonary edema, n  = 2. Two chest radiologists retrospectively evaluated the CT criteria, which consisted of 12 findings. Results The nodule ( p  = 0.015), the bronchovascular bundle (BVB) thickening ( p  = 0.001), and the interlobular septum (ILS) thickening ( p  = 0.002) were significantly infrequent in PCP. The ILS thickening was significantly frequent in drug-induced pneumonia ( p
