Unit 4 - Wk 5 Anatomy

Front 1

Back 1

Normal chest; vertebral bodies visible through shadow of mediastinum (black arrow); costophrenic angles (white arrows) where diaphragm arises from ribs

Front 2

Back 2

Kyphosis; note abnormal curvative and compression fracture

Front 3

Back 3

Hilar mass; bilateral hilar adenopathy from sarcoidosis

Front 4

Back 4

Blunted costophrenic sulcus by a small pleural effusion; left lateral view

Front 5

Back 5

Aortic Dissection; widened mediastinum and left pleural effusion

Front 6

Back 6

Aortic Aneurysm; ascending aorta visible on right heart border; descending thoracic aorta swings far away from spine and is normally not this visible

Front 7

Back 7

Aortc Dissection; intimal flap

Front 8

Back 8

Widening of the mediastinum; substernal thyroid mass; displaced trachea (black arrow) characteristic

Front 9

Back 9

Anterior medistinal lymphadenopathy; normally there is a clear space behind the sternum; this is a pt with lymphoma, adenopathy = most frequent reason that retrosternal clear space is obscured

Front 10

Back 10

Mediastinal adenopathy from Hodgkins dz; lobulated border due to conglomeration of enlarged lymph nodes that produce the mass

Front 11

Back 11

Enlargement of the cardiac silhouette, left lateral position; Poisterior border of hrt does not usually overlap the thoracic spine

Front 12

Back 12

Acute pulmonary aleveolar edema; fluffy, bilateral, perihilar airspace dz with indistinct margins sometimes described as bat wing or angel wing configuration

Front 13

Back 13

Silhouette sign, right middle lobe pneumonia

fluffy, indistinctly marginated airspace disease

1. is in contact with the right heart border
2. the dz is the same raidographic density as the heart

Front 14

Back 14

Aspiration; right and left lower lobes

Front 15

Back 15

Kerley lines; appear when connective tissue near the bronchoarterial bundle distends with fluid

Produced in pts with CHF producing the prominence of the pulmonary intesttiial markings

Front 16

Back 16

Rheumatoid lung; prominent markings at both lun gbases have a predominatly reticular appearance

Front 17

Back 17

BAT-WING (ANGEL WING) PATTERN OF PULMONARY EDEMA.The radiographic findings of pulmonary alveolar edema include fluffy, indistinct, and patchy airspace densities frequently centrally located and sparing the outer third of the lung. This is called the bat-wing (bat's-wing) or butterfly pattern, and it is suggestive of pulmonary edema versus other airspace diseases such as pneumonia.

Front 18

Back 18

PULMONARY INTERSTITIAL EDEMA (A) VS. PULMONARY ALVEOLAR EDEMA (B). The key findings in pulmonary interstitial edema (A) include thickening of the interlobular septa (Kerley B lines), peribronchial cuffing, pleural effusion, and fluid in the fissure. The heart is also enlarged in this patient who had congestive heart failure. The key findings in pulmonary alveolar edema (B) are fluffy airspace densities, frequently perihilar in distribution and sparing the outer third of lungs. Pleural effusions are frequently present when the edema is cardiogenic in origin, as in this case with large, bilateral pleural effusions (closed black arrows)).

Front 19

Back 19

Emphysema; note the distended, intercommunicating sac like spaces in the central area of acini

Front 20

Back 20

Emphysema; hyperinflation, flattening of diaphragm (esp on lateral exposure)

Front 21

Back 21

Lungs of a pt who died from CF; extensive mucous pluggin gand dilation of the tracheobronchial tree; green color is associated with Pseudomonas infections

Front 22

Back 22

Signet ring sign of bronchiectasis

Front 23

Back 23

Small cell carcinomas of the lung; characterized by the presence of small, uniform, oval cells with little cytplasm; neuroendocrine neoplasm and can secrete ectopic hormones such as ACTH, ADH and calcitonin

Front 24

Back 24

Apical lung mass (pancoast tumor) in apex of the left lung which has eroded into the chest wall
