Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are clear without focal consolidation . There increased interstitial markings with possible nodular component seen throughout the lungs . Is uncertain if this is due to combination of atelectasis given slightly low lung volumes and contribution from overlying known osseous metastases however possibility of tiny pulmonary nodules is also possible . No pleural effusion or pneumothorax is seen . The cardiac and mediastinal silhouettes are unremarkable . Right - sided Port - A - Cath is present distal tip terminating overlying the right atrium . Known diffuse osseous mets demonstrated as generalized increased sclerosis better seen on prior CT examination .
    OUTPUT:
    
Increased interstitial markings with some areas that appear nodular . It is uncertain if this is due to vascular crowding and overlying osseous metastases , or given patient 's history , the possibility of tiny pulmonary nodules from metastases . Consider CT scan to further evaluate if desired . Diffuse osseous mets re-demonstrated , better seen on prior CT examination .
