Brief Answer:
There is no brain tumor in your case.

Detailed Answer:
Hello and welcome to "Ask a Doctor " service.

I have read your query and here is my explanation.

Migraines and trigeminal neuralgia are not caused or linked with any brain tumor, these are chronic benign conditions.

Since the MRI with contrast enhancement resulted okay chances of brain tumor are nearly zero.

So, don't worry about any brain tumor, it is not your case, discuss with your Neurologist about the correct diagnosis and treatment for your symptoms.

Hope you found the answer helpful.

Let me know if I can assist you further.
