74-year-old man presents with dyspnea and orthopnea. CT shows thickening of the interlobular septa (Kerley B lines), peribronchial cuffing, and enlargement of the lobular arteriole in the right lower lobe. There is a suggestion of vasoconstriction of the arteriole as it enters the secondary lobule. ground glass changes in the some of the secondary lobules on the left and perhaps mosaic attenuation vs normal secondary lobule at the right base are noted. Additionally, there are small bilateral effusions right greater than left. The mild irregular shape of the effusions suggests that they are partially loculated. These findings indicate moderate congestive heart failure with interstitial edema.
