Chapter 11: Chest And Retroperitoneum Flashcards
The visceral pleura covers each ______
Lung
What is the pleural space
The area between the visceral and parietal pleura. Normal amount of fluid is located there to help lungs slide
What is a pleural effusion
Excessive fluid accumulation around the lung in the pleural space
Describe transudate pleural effusion
Results from an imbalance in oncotic and hydrostatic pressure
Describe exudate pleural effusion
Results from inflammation or a reduction in lymphatic drainage
What is parapneumonic efffusion
Pleural effusion associated with pneumonia
What is empyema
Pleural effusion with pus
What is pneumothorax
Caused by a thoracentesis. Air between the 2 pleural layers
Pneumothorax is better visualized with what imaging modality
Xray
With M-Mode, pneumothorax will demonstrate what sign
Barcode sign (aka stratosphere sign)
A normal M-Mode finding of a lung sliding will show what sign
Seashore sign
During childhood the thymus produces what cells
T-cells (specialized lymphocytes)
What chest masses can be analyzed with ultrasound
Tumors of the mediastinum like Lymphomas, thymomas
And superficial lung masses too
Ped petients may be evaluated for what kind of stuff in the chest
Pulmonary sequestration
Congenital cystic adenomatoid malformation
What is lung consolidation
Normal air in the alveoli is replaced with fluid, inflammation and neoplastic cells
Lung consolidation can be caused by what
Pneumonia, hemorrhage, pulmonary edema, carcinoma
What does lung consolidation look like
Similar to liver tissue, with internal echoes (air)
Pleural effusion may be seen too

Pelvis
What is the crura of the diaphragm

The psoas muscle is seen ________ to the kidney and closer to the _______
Posterior, spine
The quadratus lumborum is seen _______ and _______ to the kidney
