So, neuroendocrine tumors can be
0:02
functional or non-functional.
0:04
Once they are functional, they are detected
0:06
earlier because of their hormone secretions.
0:08
And if they are non-functional, they are detected
0:10
later because they grow before presenting
0:13
with abdominal pain or other symptoms due
0:15
to the mass effect on the overlying organs.
0:18
Non-functional NETs (Neuroendocrine Tumors) are usually large and necrotic
0:21
when detected and can sometimes mimic SPN (Solid pseudopapillary neoplasm).
0:24
But again, gender and
0:26
location are more important.
0:28
In making a diagnosis, usually, necrosis is mostly
0:30
central and they do not have hemorrhagic content.
0:32
Hemorrhage is more common with SPN.
0:35
Fifty percent of non-functional tumors, once they
0:36
grow and become more than 5 cm in size, have
0:39
the potential to be possibly malignant
0:41
and undergo metastasis when detected.
0:44
And once they are cystic, they
0:46
undergo degeneration and growth, but
0:48
the evident enhancement during the
0:50
arterial phase will still be there.
0:52
In the retained parenchyma, so you can
0:54
differentiate based on those characteristics on
0:57
imaging, but again there are other ways like doing
1:00
tumor markers or urine HIA or chromogranin to
1:04
differentiate whether it is NET or SPN.
