Early Radiologic Diagnosis of Pulmonary Infection in Febrile Neutropenic Patients: A Comparison of Serial Chest Radiography and Single CT Chest

<div>Images in a 35-year-old male with acute myeloid leukemia who had positive chest symptoms and serum galactomannan test. (A) Baseline chest film shows opacities at right upper and right lower lungs. (B) Chest film on second day of febrile neutropenia (ANC = 0 <i>μ</i>L) shows improvement of previous opacities with no new opacity. (C) Chest film on fifth day of febrile neutropenia (ANC = 0 <i>μ</i>L) shows no abnormal opacity. (D–E) Axial and coronal CT chest on seventh day of febrile neutropenia (ANC = 0 <i>μ</i>L) reveals subtle ground-glass attenuation at right upper lobe (arrows). This case was evaluated as false-negative chest radiograph and true-positive CT chest.</div>
