Pathologies Flashcards
How many are there?
8
State all 8 pathologies:
COPD- Emphysema
Pneumonia/infection
Cancer
Pleural effusion
Pneumothorax
Cardiomegaly
Tubes, lines & clips
Hiatus hernia
How can be COPD- EMPHYSEMA identified?
Chronic obstructive pulmonary disease
- Abnormal permanent enlargement of the airspaces
-caused by smoking
How can Pneumonia be identified in chest xray
Alveolar air replaced with fluid
Obscures lung markings
Airspace opacification - Consolidation
Patchy or extensive
+/- atelectasis (collapse)
Air bronchograms in progressive disease
Nasogastric
Tube (NGT)
A nasogastric (NGT) tube is a thin, soft tube that goes in through the nose, down the throat, and into the stomach.
Deviation of trachea towards
means collapse, fibrosis, alectasis,
Deviation of trachea away
is effusion, pneumothorax, tumours
Cancer
CXR cannot determine invasive features of lesions
Masses may be central or peripheral
Central (squamous cell carcinoma and small call carcinoma)
Peripheral (Mostly adenocarcinoma and large cell carcinoma)
Lung hilar mass
Right hilum abnormal
* Mediastinum widened
due to lymph node
enlargement
* Pleural effusion also
present
How to identify PULMONARY
METASTASES
Secondary malignant
tumours
* Originate from cancer in
separate organ
* Single or multiple
rounded nodules
* Peripheral distribution
and usually bilateral
How can right upper lobe collapse be identified?
- Dense opacity in right
upper zone due to lobar
collapse - Highly likely that a mass
is obstructing the right
upper lobe bronchu
How to identify pleural effusion?
- Accumulation of fluid in the pleural space
- Erect position (supine and semi-erect radiographs mask findings)
On an erect radiograph: - Small volume only seen on lateral CXR (posterior costo-phrenic recess)
- > 250ml - radiopaque meniscus at costo-phrenic angle(s)
- Large volume can create mass effect and collapse
Causes: Infection | heart failure | malignancy | cirrhosis
How do you identify PNEUMOTHORAX/ PTX
Spontaneous | Traumatic | Tension
Sudden, often severe onset chest pain and SOB
- Air in pleural space (Commonly apical on erect radiograph)
- Lung edge visible with no lung markings peripheral
- Collapse of lung (towards hilum)
Closed or penetrating
- Penetrating: rib # +/- subcutaneous emphysema
Intercostal catheter (ICC) used to drain large volume
Tension of the pneumothorax
Air collection constantly enlarging
- Deviation of the trachea away
- Compression of the contralateral side
- Mediastinal shift
- ICC inserted to drain air from pleural
space
How do you identify hiatus hernia?
Air fluid level behind heart.
- faint gap behind the heart on CXR
