Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with earlier the same day , the left apical component of the pneumothorax appears similar . The component along the medial portion of the lung near the aortic knob is similar , possibly very slightly larger . The hydro pneumothorax at the left lung base is slightly different in configuration , but not clearly larger . The lateral view shows an additional retrosternal component . The left chest tube and left indwelling catheter are both similar in position and configuration . Slight irregularity in the proximal portion of the catheter near the port has been stable and likely relates to the construction of the Port - A - Cath , but clinical correlation is requested to confirm this . The cardiomediastinal silhouette is similar , grossly midline , allowing for slight rotation . There is a small right effusion , which is also similar . Probable atelectasis at the right lung base . Eventrated contour of the right hemidiaphragm is unchanged . No right apical pneumothorax is identified .
    OUTPUT:
    
No definite change in size of the left - sided pneumothorax . The component adjacent to the aortic knob may be very slightly larger . The hydro pneumothorax at the left base is slightly different in configuration , but not clearly larger . The lateral view demonstrates a retrosternal component . Although none of these enumerated components are individually especially large , taken together , the overall size of the pneumothorax is appreciable ( small to moderate ) . The chest tube and Port - A - Cath are unchanged . Clinical correlation regarding the Port - A - Cath is requested --___ see comment above .
