When we consider the diagnosis of

0:03

extramedullary hematopoiesis,

0:05

we have to recognize that one of its manifestations

0:07

is paraspinal masses in the posterior

0:10

mediastinum. This was a chest CT scan that really

0:15

a neuroradiologist shouldn't be looking at.

0:17

However, when we evaluated the patient for

0:21

potential spinal pathology,

0:24

we started note that there were nodules that were

0:27

present in a paraspinal location bilaterally at multiple

0:32

levels that were not extending into the neural foramen.

0:35

So not a CNS process,

0:38

but as you can see, a multilevel,

0:42

multilobulated process that is predominantly in a

0:46

paraspinal location. On the coronal

0:49

reconstructed images,

0:51

you can get a better sense of the multiple nodular

0:56

paraspinal processes that do not extend into the neural foramina.

1:00

And this was an example of a patient who had

1:05

extramedullary hematopoiesis as part of a manifestation

1:08

of a myelodysplastic syndrome.
