    INPUT: Frontal and lateral chest radiographdemonstrates a linear plate like opacity within the left lower lobe most consistent with platelike atelectasis . Heterogeneous right lower lobe opacity is only seen on frontal view . No pleural effusion or pneumothorax . Heart size , mediastinal contour , and hila are unremarkable . A right porta cath tip is seen in the low SVC . Limited assessment of the upper abdomen is within normal limits .
    OUTPUT:
    
1 . Linear plate like atelectasis in the left lower lobe . 2 . Heterogeneous opacity in the right lower lobe is most consistent atelectasis however superimposed infection can not be excluded . Of note CT is more sensitive in detection of atypical infection in immunocompromised patients .
