Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Four frontal images of the chest were obtained . One pair of images demonstrates an NG tube overlying the right chest . Due to patient positioning , it is unclear exactly where this tube is located , particularly since there is no lateral view . The other pair of images demonstrates an NG tube with the tip in the stomach . After discussing with the medical team , it appears that this is the latter pair of images . Again seen is a left lower lobe parenchymal density and pleural effusion , unchanged from previous imaging . The right lung is clear . There is no evidence of flash pulmonary edema and , given that the opacity seems localized to the left lower lobe , a pneumonic or pleuritic etiology is more likely . This could include a possible infectious etiology in the left lower lobe . The cardiomediastinal silhouette can not be fully assessed due to bordering left lung opacities , but the heart appears normal in size . Gaseous distention of the large and small bowel is again seen .
    OUTPUT:
    
Nasogastric tube is seen on the second pair of images to be in place with the tip in the stomach . Left lower lobe opacity and left pleural effusion suggestive of a left lower lobe pneumonia or focal process rather than a generalized flash pulmonary edema . These findings were communicated by phone to Dr . ___ at 2 :44 p .m .
