    INPUT: Unable to assess erosions of the sternum ___ malignancy ___ costochondritis in current radiographs . Patient has multiple chronic pulmonary abnormalities that have since progressed . In the lower lungs , there is interstitial infiltration described as mild traction bronchiectasis and cortical reticulation on recent CT in ___ . There also irregular areas of consolidation with bronchiectasis in the right upper and left upper lobe which have been noted to evolve from interstitial infiltration noted previously on recent CT . No pleural effusion ___ pneumothorax is seen . The cardiac and mediastinal silhouettes are unchanged . Calcified aortic knob again noted .
    OUTPUT:
    
Unable to assess erosions of the sternum ___ malignancy ___ costochondritis in current radiographs . Consider chest CT for further evaluation . However , chest CT may still be nondiagnostic for costochondritis ___ ___ syndrome . Multiple areas of pulmonary abnormalities , including areas of interstitial infiltration of lower lobes and areas of consolidation and bronchiectasis in the upper lobes , have progressed since radiographs from ___ . An alternative differential to nonspecific interstitial pneumonia , which has previously been raised as a possibility , is the possibility of pulmonary fibroelastosis .
