Chest radiographs are of limited value in predicting the causative pathogen but are of good use to determine the extent of pneumonia and to detect complications (i.e., cavitation, abscess formation, pneumothorax, pleural effusion), to detect additional or alternative diagnoses, and, in some cases, to guide invasive diagnostic procedures. Risk factors for the development of staphylococcal pneumonia include underlying pulmonary disease (e.g., COPD, carcinoma), chronic illnesses (e.g., diabetes mellitus, renal failure), or viral infection. The lower lobes contrast-enhanced CT image shows a mixed opacity of consolidation (arrow) and ground-glass opacity (small arrows) consistent with lobar pneumonia tend to be affected, and the radiographic pattern is similar to that seen with S. ./cache/cord-007797-toam6r5y.txt ./txt/cord-007797-toam6r5y.txt
