Question 1

what does fluffy infiltrates bilaterally in the lung suggest?

Answer 1

mononuclear inflammation in the interstitium

Question 2

what does acute supprative pneumonia look like on xray?

Answer 2

dense opacity/consolidation restricted to one lobe

Question 3

dense consolidation right around the hilum on xray indicates what?

Answer 3

granulomatous inflammation

Question 4

what does liquifactive necrosis w/ a lung abcess look like on xray?

Answer 4

dense opacity/consolidation, not the entire lobe, but w/ a liquid/air line

Question 5

histoplasma capsulatum

Answer 5

causes intracellular budding yeast w/in macrophages

causes granulomas that resemble TB, but w/ more fibrosis

Question 6

pneumocystis jirovecii

Answer 6

opportunistic pathogen seen in people with suppressed immune system- sampled by “induced sputum” or bronchoalveolar lavage

typically little inflammation

Question 7

ecthyma gangrenosum

Answer 7

usually infection w/ pseudomonas auerginosa

necrosis/inflammation associated w/ bacteremia

neutropenia increases risk of disease- treatable w/ antibiotics

Question 8

pseudomonas folliculitis

Answer 8

normal inflammatory response to pseudomonas in hair follicles

Question 9

candida albicans

Answer 9

budding yeast- can cause esophagitis- (oropharynx called thrush)

creates pseudomembrane

associated w/ acute suppurative inflammation

Question 10

diagnosis of CMV

Answer 10

inclusion bodies

serologic- IgGs

measuring viral load - qPCR

Question 11

toxoplasma encephalitis

Answer 11

necrosis and destruction of brain tissue- found at gray/white tissue

multiple lesions

caused by toxoplasma gondii- caused by reactivation rather than primary

necrosis of neurons and microglial cells

variable acute inflammatory rxn
