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.
