Case: Random Nodules in Histoplasmosis

HIDE
PrevNext

0:01

Look at all these nodules just all over the place.

0:05

And so these nodules clear there.

0:07

There's involvement of the fissure, subpleural, lung,

0:10

and so we see all those nodules, and

0:12

because it has all that subpleural involvement,

0:14

now we know we're dealing with a case of either

0:17

per lymphatic nodules or random nodules.

0:19

Central li nodules are out.

0:21

These are just all over the place.

0:23

If we look carefully, let's see,

0:25

let's look at a slice like right here.

0:28

So these nodules, these look random.

0:32

These are entropic, so some

0:33

nodules clustered closer together.

0:35

Other nodules, like there's other portion lungs

0:37

where there's very few nodules,

0:39

but they're all over the LA place,

0:41

so it's not just clustered in some areas, it's just

0:44

that these nodules, some

0:45

of these nodules are closer

0:46

together, some are further apart.

0:47

And so tropic nodules like these mean random nodules,

0:52

and it means that this patient has some sort

0:54

of hematogenous something, whether it's infection

0:57

or metastatic disease.

0:59

In this case, this is a case of disseminated histoplasmosis.
