Can tinnitus be caused by a tumor?


Hello doctor, I have been experiencing tinnitus for some time.
Initially, I thought it was due to anemia, but I have since treated my anemia, and the tinnitus persists.
It usually occurs after maintaining a fixed posture for a while (for example, looking down at my phone).
If I quickly change my position, the tinnitus stops.
I have also experienced tinnitus while sleeping (once).
In very quiet places, I can hear a continuous ringing sound (not very loud, but noticeable; I am unsure how long it has been going on, as I only recently became aware of it).
The tinnitus is not consistently on one side; sometimes it is in my left ear and sometimes in my right ear, but my left ear feels more congested.
I previously underwent a hearing test and a brain wave test, both of which were normal.
I have a history of nasal allergies, and an ENT specialist mentioned that my nasal issues might be affecting my ears, suggesting possible Eustachian tube dysfunction.
I also experience slight dizziness occasionally, but not daily; the dizziness is more pronounced when using the computer.
I would like to know if this could be autonomic nervous system dysfunction or if there is a possibility of a brain tumor or acoustic neuroma.
If I go to the hospital, will the doctor arrange for an MRI?

Hello, Ms.
Tsai: There are various causes of tinnitus, and most patients experience improvement after rest.
If the symptoms persist, it is recommended to consult a neurologist for further evaluation.

Tinnitus, or ringing in the ears, can indeed be a perplexing symptom, and it can arise from a variety of causes. Your description of the tinnitus being positional—worsening when you hold a certain posture, such as looking down at your phone—suggests that it may be related to changes in pressure or blood flow, possibly due to neck or head positioning. However, the concern about a potential tumor, such as an acoustic neuroma (a benign tumor on the vestibulocochlear nerve), is valid and worth discussing.

Acoustic neuromas are rare, slow-growing tumors that can cause tinnitus, hearing loss, and balance issues. They typically present with unilateral symptoms, meaning they affect one ear more than the other, but they can occasionally present bilaterally. The fact that your tinnitus is not consistently one-sided and that you have had normal hearing tests and brain wave studies makes an acoustic neuroma less likely, but it does not completely rule it out.

Your history of allergies and nasal congestion could also contribute to your tinnitus. Eustachian tube dysfunction, which can occur with allergies, can lead to pressure changes in the ear that may manifest as tinnitus. The mild dizziness you experience, particularly when using the computer, could also be related to neck strain or tension, which is common in individuals who spend long hours in front of screens.

Given your symptoms and the fact that they have persisted despite treating your anemia, it would be prudent to follow up with an ear, nose, and throat (ENT) specialist. They may recommend further evaluation, including imaging studies like an MRI, especially if there are any red flags such as significant changes in your hearing, persistent dizziness, or if the tinnitus worsens. An MRI can help rule out any structural abnormalities, including tumors.

In terms of autonomic nervous system dysregulation, while it is possible that stress or anxiety could exacerbate your symptoms, the presence of tinnitus alone does not confirm this diagnosis. It is essential to consider all potential causes, including physical factors like posture, allergies, and possible neurological issues.

In summary, while your symptoms could be related to benign causes such as Eustachian tube dysfunction or tension, it is essential to consult with a healthcare provider for a thorough evaluation. They can determine whether further testing, such as an MRI, is necessary based on your clinical presentation. Keeping a symptom diary, noting when the tinnitus occurs and any associated factors, can also be helpful for your healthcare provider in making a diagnosis.
