Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar study dated ___ . Heart size is unchanged . Thoracic aorta as before . There is now a rather well - demarcated local mass occupying the right tracheo = bronchial angle and bulging in round shape , well demarcated to the right , thus occupying and widening the superior right - sided mediastinum . Patient is status post VATS wedge resection in the right upper lobe area . The latest followup examination of ___ demonstrated satisfactory findings with absence of pneumothorax and chest tube removal . A certain degree of prominence of the right upper mediastinum existed already at that time . This finding , however , has changed in as much as the apparent mass shows increased prominence . There are no new pulmonary parenchymal abnormalities present , and the lateral and posterior pleural sinuses remain free .
    OUTPUT:
    
Increasing soft tissue prominence in right superior mediastinum occupying the right tracheobronchial angle . The prominence is increasing since the next preceding chest examination two weeks ago . As the patient was recently operated for a pulmonary malignancy , right upper lobe finding is worrisome for local malignant metastasis . Depending on clinical situation , confirmation of these findings with a repeat chest CT might be considered .
