Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A small left apical pneumothorax is stable to minimally increased in size from ___ 33 . Unilateral left - sided pleural thickening and left - sided rib cage deformity is unchanged from the recent prior . Bandlike opacity in left perihilar region is not fully evaluated by chest radiography but appears unchanged . Cardiomediastinal contours are unchanged .
    OUTPUT:
    
Left apical pneumothorax is stable to minimally increased in size from ___ 33 . Unilateral left - sided pleural thickening is potentially posttraumatic in the setting of adjacent rib deformities , but comparison to older radiographs would be helpful to ensure stability and to exclude a malignant pleural process such mesothelioma or metastatic adenocarcinoma . A bandlike opacity in the left juxta hilar region may also be assessed for retrospective stability at that time .
