Pleural Space Flashcards
What is the pleural space?
potential space located between the parietal pleurae on the thoracic body wall and the visceral pleurae on the lung lobes
What is the metdiastinum?
potential space on midline between the left and right parietal pleurae that reflect caudally from the thoracic body walls
What is the normal anatomy of the right and left lung lobes?
R = cranial, middle, caudal, accessory
L = cranial (with cranial and caudal subsegments), caudal
What are pleural fissures? Where are they found?
extensions of the potential pleural space between adjacent lung lobes
- R = 6th ICS between cranial and middle lobes, 8th ICS between middle and caudal
- L = 4th ICS between cranial subsegments, 7th ICS between cranial and caudal
How is lung lobe anatomy appreciated dorsally?
mostly only see a pleural fissure between the right cranial and caudal lobes and left cranial and caudal lobes
What is seen in this radiograph?
focal thickening of fissure between right middle and caudal lung lobes (8th ICS)
Lable the fissures seen on this radiograph.
R = cranial-middle, middle-caudal
L = cranial-caudal
