Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is extensive , heavy , left - sided pleural calcification extending along the full extent of the left hemithorax , particularly laterally , and appears to involve the left costophrenic angle , and with left lung volume loss . Slight blunting left costophrenic angle is felt to likely be due to pleural thickening . No focal consolidation is seen on the right . Slight prominence of the right hilum is noted . The cardiac silhouette is top - normal to mildly enlarged . The aorta is calcified and tortuous . No overt pulmonary edema is seen .
    OUTPUT:
    
Left - sided fibrothorax . Given given reported prior history of pulmonary tuberculosis fibrothorax may be due to history of tuberculous pleuritis . Differential diagnosis would also include a history of prior infection / empyema or hematoma . Mediastinal pleura appears spared , however correlate with prior imaging to document long - term stability , and if none , need for outpatient CT . Mildly prominent right hilum most likely due to prominent pulmonary vessels however , nonurgent chest CT could be obtained to assess for underlying lymphadenopathy .
