Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a midline tracheostomy tube . No focal consolidation is seen . There is no large pleural effusion or pneumothorax . The cardiac and mediastinal silhouettes are stable . In the right infrahilar region , there is a 2 .3 x 2 .3 cm rounded opacity which while could relate to vascular structures , an underlying nodule is not excluded , and further evaluation is recommended with chest CT . No focal consolidation is seen . No pleural effusion or pneumothorax . Cardiac and mediastinal silhouettes are unremarkable .
    OUTPUT:
    
2 .3 x 2 .3 cm rounded opacity in the right infrahilar region conceivably could be vascular ; however , is quite round and raises concern for underlying pulmonary nodule . This may have been obscured on the prior study . Suggest oblique views or chest CT for further evaluation . The remainder of the lungs show no focal consolidation .
