3. • Fig C 25-1 Mediastinal lymphadenopathy in
sarcoidosis. (A) Frontal and (B) lateral views of
the chest demonstrate enlarged mediastinal
lymph nodes (arrows).

4. • Fig C 25-2 Aneurysm of the left subclavian
artery. Left superior mediastinal widening in
an elderly woman without chest symptoms.43

5. • Fig C 25-3 Bronchogenic cyst. (A) Frontal and
(B) lateral views of the chest demonstrate a
smoothwalled, spherical mediastinal mass
(arrows) projecting into the left lung and left
hilum.

6. • Fig C 25-4 Bronchogenic cyst. (A) Frontal and
(B) lateral views of the chest demonstrate a
huge middle mediastinal mass (arrows, B)
protruding to the right and filling much of the
lower half of the right hemithorax. The patient
was asymptomatic

7. • Fig C 25-5 Aortic transection. Frontal chest radiograph
taken immediately after trauma demonstrates
mediastinal widening, obscuration of the aorta,
deviation of the trachea to the right, and downward
displacement of the left main-stem bronchus.51

8. • Fig C 25-6 Acute mediastinitis due to rupture of the
esophagus. Plain radiograph demonstrates linear lucent
shadows (arrows) that represent localized mediastinal
emphysema and correspond to the fascial planes of the
mediastinal and diaphragmatic pleurae in the region of the
lower esophagus.52

9. • Fig C 25-7 Chronic sclerosing mediastinitis. Venogram
shows smooth tapering of the lower portion of the
superior vena cava. This 38-year-old woman had
varicosities over her upper abdomen and lower chest.52

10. • Fig C 25-8 Congenital intrapericardial hernia.
(A) Frontal and (B) lateral views in an
asymptomatic elderly man show loops of
bowel in the chest conforming to the left
pericardial border.53
