Introduction: Fever & Infection

HIDE
PrevNext

0:00

Clinical indications of fever oftentimes will be pneumonia. And when we

0:04

think about pneumonia all commerce, so this could be bacterial, this could

0:08

be viral, this could be fungal, it could be inhalation. We have obviously

0:12

a lot of attention paid recently to COVID19 pneumonia; it could be pericarditis

0:18

or empyema. Things that are infective or infectious, and

0:22

irritating or inflammatory are going to cause and can cause fever.

0:26

So when you think about imaging to consider PA and lateral chest radiograph,

0:31

great screening tool, chest CT provides further characterization and may

0:36

actually identify subtle findings that you're just not able to see on radiograph.

0:41

So not uncommon that patients who have apparently clear lungs or lungs that

0:45

don't look like there's anything lobar or focal going on, on the chest

0:51

CT when there's appropriate clinical suspicion may reveal small subtle areas

0:55

of infection or inflammation that align very nicely and

1:01

are characterized by pneumonia. So keep that in mind as well.

1:05

So again, when you're looking at the imaging findings of pneumonia,

1:09

some of the patterns can help differentiate whether or not this is bacterial,

1:13

viral or fungal, and we'll talk more about that

1:17

in the rest of the session.
