<p>Both, Pre &amp; post contrast 5 &amp; 10 mm. thick slices of the lungs are recorded after giving oral contrast medium.</p><p><strong>Observations:</strong></p><p>The scanogram shows an an enlarged heart CTR 15/28.5. &nbsp;The aorta is normal. There lung fields are clear with oblitration of the right costophrenic sulci. The bony thorax is within normal limits.&nbsp;</p><p>Serial axial pre and post contrast images shows shows normal lung parenchyma with normal attenuation on the left hemithorax. There is a localized inhomogeneous soft tissue dense mass seen in the right lower lung zone anteriorly with oblitration of the right costophrenic sulci likely long standing effusion. &nbsp;There is no mediastinal lymphadenopathy. No cavitation, calcification, mass or any other significant lesions. Trachea and main bronchi are normal. Bronchial tree is normal. No evidence of Bronchiectasis. Pleura on both sides are normal.&nbsp;The bony cage is normal. No evidence of PTB or metastasis seen.&nbsp;</p><p><strong>CONCLUSION:- Right anterior lobe pneumonic changes involving the right costophrenic sulci likely fibrotic</strong></p>
