Here is yet another left-sided jugular tumor.

0:05

And as we scroll the non-contrast and contrast

0:09

enhanced images, down to the skull base,

0:12

you see that this lesion is bright in signal intensity

0:17

on the T1-weighted scan before contrast.

0:20

However, it does show avid contrast enhancement.

0:24

So this is another example of the so-called salt and

0:28

pepper look with the bright and the dark signal

0:31

intensity in the mass, even before contrast,

0:35

secondary to the matrix of the lesion,

0:37

as well as the flow voids of the vessels

0:41

accounting for the pepper.

0:43

And this lesion as well seems to grow into the

0:47

distal-most portion of the sigmoid sinus, and then,

0:51

as you can see, grows into the jugular vein,

0:54

hence giving us the high likelihood that this

0:57

represents a glomus jugulare tumor.

1:00

When you have these glomus jugulare tumors,

1:02

you really must look at the contralateral side, as

1:06

well to look for any additional paragangliomas,

1:10

be they glomus jugulare, glomus vagale,

1:13

glomus tympanicum, or carotid body tumors.

1:16

In this case, another left-sided,

1:19

isolated glomus jugulare tumor.
