Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is no focal consolidation . Streaky bibasilar opacities most likely represent atelectasis , as seen on the recent CT abdomen / pelvis performed on the same date . Small left pleural effusion . No pleural effusion on the right . No pneumothorax . Heart is mildly enlarged .
    OUTPUT:
    
1 . No pneumothorax . 2 . Small left pleural effusion with bibasilar atelectasis . 3 . Mild cardiomegaly . 4 . Although no acute fracture or other chest wall lesion is seen , conventional chest radiographs are not sufficient for detection or characterization of most such abnormalities . If the demonstration of trauma to the chest wall is clinically warranted , the location of any referrable focal findings should be clearly marked and imaged with either bone detail radiographs or Chest CT scanning .
