Pneumonia Patterns
This bacteria is the most common cause of community-acquired pneumonia
What is Streptococcus pneumoniae?
What is the left recurrent laryngeal nerve?
This is the first-line imaging modality for evaluating suspected pneumonia.
What is a chest x-ray?
This type of pleural effusion results from heart failure or cirrhosis and is typically low in protein.
What is transudate?
Increased tactile fremitus is heard over areas of this lung pathology
What is a consolidation (e.g., pneumonia)?
Pneumonia characterised by patchy, bilateral infiltrates rather than whole-lobe consolidation
What is bronchopneumonia?
Air moves into the lungs during inspiration due to this pressure change.
What is decreased alveolar pressure?
This CT technique proves the best resolution for detecting interstitial lung disease.
What is high-resolution CT (HRCT)?
A young tall man develops sudden chest pain and dyspnea after basketball. Chest x-ray shows absence of lung markings peripherally
What is spontaneous pneumothorax?
Percussion over a pleural effusion would produce this sound.
What is a dull sound?
This atypical pneumonia organism is often associated with outbreaks in schools and barracks.
What is Mycoplasma pneumoniae?
These muscles are primarily responsible for forced expiration.
What are the abdominal muscles and internal intercostals?
This radiographic sign suggests left lower lobe consolidation by obscuring the left heart border.
What is the silhouette sign?
A patient presents with dyspnea. Thoracocentesis reveals milky white pleural fluid that is rich in triglycerides. What is the most likely diagnosis?
What is chylothorax?
In bronchial breath sounds, the inspiratory and expiratory phases have this relative duration.
What is equal duration?
Pneumonia secondary to aspiration while supine most often affects this lung region
What is the posterior segment of the right upper lobe?
What is the transpulmonary pressure?
A solitary pulmonary nodule with "popcorn calcifications" on imaging is most likely this benign lesion.
What is a harmartoma?
A pleural biopsy shows malignant mesothelial cells. This finding is classically associated with exposure to what material?
What is asbestos?
Name the maneuver where whispered "99" becomes lounder over lung consolidation.
What is whispered pectoriloquy?
Klebisella pneumoniae can cause this dramatic radiological finding on chest x-ray
What is bulging fissure?
The majority of alveolar collapse in Neonatal Respiratory Distress Syndrome is due to deficiency of this substance?
What is surfactant.
A solitary pulmonary nodule is found on CT with smooth margins, dense central calcification, and no growth in two years. This nodule is most consistent with what diagnosis?
What is a granuloma?
Pleural effusions with high LDH, high protein, and low glucose levels suggest this type of underlying pathology.
What is an exudative effusion (e.g., malignancy or infection)?
A shift in the trachea towards the affected side suggests this underlying lung pathology
What is lung collapse?
