Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The right Port - A - Cath appears intact and unchanged in position . Stable bilateral lung volumes . Streaky densities at the right lung base , consistent with subsegmental atelectasis , are unchanged . Small left pleural effusion , also not significantly changed . Stable cardiomegaly and mediastinal silhouette with a right - sided neoesophagus causing apparent widening of the mediastinum . No focal consolidation to suggest pneumonia , pulmonary edema , or pneumothorax . More prominent small crescentic lucency which appears to be outlining the diaphragm and may represent a small pneumoperitoneum . Contrast from recent barium study is still demonstrated within an air - filled colon .
    OUTPUT:
    
1 . Possible small pneumoperitoneum . Recommend follow - up radiographs to assess for change . 2 . Stable right lower lung atelectasis . 3 . Stable small left pleural effusion .
