Transverse Cerebral Venous Thrombosis

I am a 30 year old man with a Bachelor degree in Clinical Neuropsychology.

I went for a MRI scan to check for trigeminal neuralgia in my right cheek and lip. No compression or whatsoever was found and the radiologist reported nothing special.

After viewing the MRI scan myself I saw a 3" white matter in the right transverse sinus.

I don't think there is a relation with the stabbing and burning pain in my cheek (it think it's muscular issue, which is gone now btw), but I am a little worried if something like a thrombus is in the transverse sinus. I'm told not to be worried as long as I have no head aches etc...

But I'm still worried... see my image.
