Flashcards in Rubins - respiratory system Deck (5):
What is pulmonary hypoplasia?
What are 3 causes?
incomplete or defective lung development (i.e. in utero) that results in fewer acini or smaler sized than normal
Compression of lung (gongential diaphramatic hernia)
Oligohydramnios (inadequate volume of amniotic fluid due to genitourinary anomalies)
Gestational congenital diaphragmatic hernia is associated with what?
specifically hypoplasia of the bronchi and pulmonary vessels
congential cystic adenomatoid malformation?
abnormal bronchiolar structions of varying sizes
presents with respriatory distress and cyanosis in first 2 years of life
affects one lobe (usually)
"multiple cyst like spaces lined by bronchiolar epithelium separated by loose fibrous tissue"
newborns: present with respiratory distress from compressed lungs
Adults: secondary infection of cyst can lead to hemorrhage or poerforation
discrete, extrapulminary, fluid filled mass lined by respiratory epithelium and limited by walls that contain muscle and cartilage
most common in middle mediastinum
Can be asymptomatic
