Q

What is this CXR showing?

A
  • RML pneumonia

28
Q

What are the two arrows on this CXR indicating?

A

  • There should never be that much air between the heart and lungs.
  • This can be caused by airway trauma, tracheal or esophageal rupture
29
Q

What is this CXR showing?

A
  • Left Pneumothorax
  • Notice the air trapping on the patient’s left lung
30
Q

What is this CXR showing?

A
  • Subcutaneous Emphysema
  • Notice the intermittent areas of radiolucency, often representing a fluffy appearance on the exterior borders of the thorax.
31
Q

What is the red arrow indicating?

A
  • Deep Sulcus Sign
  • This is an indirect indicator of a pneumothorax.
32
Q

If a child swallows a large coin, is it more likely to go down the esophagus or trachea?

A
  • Esophagus
33
Q

What is this CXR showing?

A
  • Pulmonary Fibrosis
34
Q

What is this CXR showing?

A
  • Diffuse Pulmonary Edema
35
Q

What is the classic sign on a CXR of pulmonary edema secondary to CHF?

A
  • Bat Wing Pattern
  • Enlarged Heart
36
Q

What is this CXR showing?

A
  • Post-op Left Pneumonectomy
  • There is no left lung
37
Q

What is this CXR showing?

A
  • Transverse Aortic Arch Aneurysm
38
Q

What is this CXR showing?

A
  • Cardiomegaly
39
Q

What is this CXR showing?

A
  • Aortic Dissection
  • Notice the wide mediastinum and deviation of the heart to the patient’s left side
40
Q

What sign is present when a large loop of the intestine gets shoved between the diaphragm and the liver?

A
  • Chilaiditi Sign
41
Q

What is this CXR showing?

A
  • Esophageal Rupture (Boerhaave’s Syndrome)
  • Notice small bilateral lung field and infiltrates
  • Wide mediastinum pattern
  • Air visible on bilateral sides of the heart
42
Q

What is hilar adenopathy?

A
  • Hilar adenopathy is the enlargement of lymph nodes in the hilum.
  • It can be caused by conditions such as tuberculosis, sarcoidosis, drug reactions, infections, or cancer.
43
Q

What is this CXR showing?

A
  • Bilateral Hilar Adenopathy
44
Q

Case Study: 35 y/o male with dyspnea, unplanned weight loss over 3 months.

A
  • Pulmonary lesion on patient’s left lung
  • Thin-walled cavity is noted in the left midlung. Most likely cancerous.
  • This finding is most typical of squamous cell carcinoma (SCC).
45
Q

Case Study: 65y/o with a month worth of dyspnea, occasional productive cough, and fever

A
  • LUL Atelectasis: Loss of heart borders/silhouetting.
  • Notice over inflation on unaffected lung

Q

What is this CXR showing?

A
  • COPD: increase in heart diameter, flattening of the diaphragm, and increase in the size of the retrosternal air space.

50
Q

What is this CXR showing?

A
  • Pseudotumor: fluid has filled the minor fissure creating a density that resembles a tumor (arrow). Recall that fluid and soft tissue are indistinguishable on plain film.
  • Further analysis, however, reveals a classic pleural effusion in the right pleura.
  • Note the right lateral gutter is blunted and the right diaphram is obscurred.
51
Q

What is this CXR showing?

A
  • Pneumonia: a large pneumonia consolidation in the right lower lobe.
  • Knowledge of lobar and segmental anatomy is important in identifying the location of the infection.
52
Q

What is this CXR showing?

A
  • Pulmonary Edema secondary to CHF
  • A great deal of accentuated interstitial markings, curly lines, and an enlarged heart.
  • Normally indistinct upper lobe vessels are prominent but are also masked by interstitial edema.
53
Q

What is the CXR showing?

A
  • Chest wall lesion: arising off the chest wall and not the lung
54
Q

What is the CXR showing?

A
  • Pleural effusion: Note loss of left hemidiaphragm.
  • Fluid drained via thoracentesis
55
Q

What is the CXR showing?

A
  • Lung Mass
56
Q

What is the CXR showing?

A
  • Small Pneumothorax: LUL
  • Notice that thin white line, that is the lung being shoved down by the pneumothorax
57
Q

What is the CXR showing?

A
  • Right Middle Lobe Pneumothorax: complete lobar collapse and deep sulcus
58
Q

What is the CXR showing?

A
  • Metastatic Lung Cancer: Multiple nodules seen
59
Q

What is the CXR showing?

A
  • RUL pulmonary nodule
60
Q

What is the CXR showing?

A
