Does my aorta look normal? FINDINGS: No enlarged axillary or mediastinal adenopathy. The hila do not appear enlarged, detail is limited due to lack of contrast. There are calcified lymph nodes in the left hilum in keeping with old granulomatous disease. No pleural or pericardial effusions. Atherosclerotic calcification is present within the thoracic aorta. Evaluation of the aorta is limited due to lack of intravenous contrast. The sinotubular junction measures approximately 4.1 x 4.1 cm in the AP and transverse dimensions. The ascending aorta at the right pulmonary artery measures 4.0 x 3.6 cm and the proximal arch measures 3.6 x 3.7 cm. The descending thoracic aorta at the level of the right pulmonary artery measures 3.1 x 3.1 cm at the diaphragmatic hiatus the aorta measures 3 x 3 cm. There is paraseptal and centrilobular emphysematous changes. There is scarring in the medial right middle lobe there is also pleural parenchymal scarring noted in the lateral lingula it was evident on the previous CT scan of the abdomen and pelvis dated 1/5/2009. There are a few calcifications along the left major fissure and left lower lobe related to granulomatous disease. Apical pleural parenchymal scarring is noted. The adrenal glands are normal. There are mild degenerative changes in thoracic spine. No compression fractures identified. IMPRESSION: Paraseptal and centrilobular emphysematous changes. There are calcified granulomatous lymph nodes in the left hilum and a few scattered calcifications also noted in the left lower lobe. Upper limits of normal of the ascending thoracic aorta.
