Hi Doc, please explain to me what is the meaning of these findings... - There are linear densities in the right uppe rlung. - The cardiomediastinal silhouette appears prominent. - Trachea is at midline - Costopheric sulci are intact. Impression: 1.upper lung linear densities may reflect fibrosis. 2. prominent appearance of the cardiomediastinal silhouette may be secondary to magnification from poor inspiratory effort. correlate with clinical and laboratory findings if there is concern for cardiomegaly. the person is treated before and cured (TB). It s been years. THANK YOU your opinion is much appreciated.
