Yes, a brain tumor, especially an acoustic neuroma (vestibular schwannoma), can absolutely cause dizziness and tinnitus (ringing in the ears) because it grows on the nerve connecting the ear to the brain, affecting both hearing and balance. While these symptoms often point to inner ear issues, when they occur together, especially if they affect only one side (unilateral), they are significant warning signs of a potential tumor, alongside other signs like headaches, balance problems, or facial numbness, and require medical investigation with imaging like an MRI.
Tinnitus can be a symptom of brain tumours, and together with hearing loss, dizziness, facial numbness, difficulty swallowing and headaches, is a particular red flag for acoustic neuroma, also known as vestibular schwannoma.
While a brain tumor isn't likely to be a direct cause of dizziness, some tumors can trigger headaches and bouts of nausea and vomiting that may be associated with a dizzy feeling. This is especially true if an individual experiences frequent vomiting and becomes dehydrated.
Acoustic neuroma. An acoustic neuroma grows between the vestibulocochlear nerve and the facial nerve inside the inner ear canal. The tumor's pressure on these nerves can cause hearing loss, ringing in the ear and facial weakness.
General signs and symptoms caused by brain tumors may include: Headache or pressure in the head that is worse in the morning. Headaches that happen more often and seem more severe.
Some of the first signs of a brain tumor may include:
Suspect a brain tumor if experiencing persistent or severe headaches, seizures, cognitive changes, vision problems, personality changes, balance issues, fatigue, nausea/vomiting, speech difficulties, or loss of smell. Seeking medical evaluation for these symptoms is important.
Brain tumor red flags include persistent, worsening headaches (especially in the morning/night), new-onset seizures, unexplained nausea/vomiting, vision changes (blurred, double), balance/coordination issues (clumsiness, trouble walking), significant personality or behavioral shifts, weakness/numbness on one side, and speech difficulties (slurring, trouble finding words). These symptoms often stem from increased pressure or direct interference with brain functions, and their gradual or sudden appearance warrants medical attention.
These blood flow changes can cause tinnitus or make tinnitus more noticeable. Other chronic conditions. Conditions including diabetes, thyroid problems, migraines, anemia, and autoimmune disorders such as rheumatoid arthritis and lupus have all been associated with tinnitus.
Will a brain MRI show ear problems? Yes, a brain MRI will look at your ear's inner structures and auditory nerves as part of the scan, though it's not routinely used for hearing problems. An IAM MRI is more effective at getting a detailed image of the ears and surrounding areas.
If you have vertigo due to problems in the brain (central vertigo), you may have other symptoms, including: Difficulty swallowing. Double vision. Eye movement problems.
Symptoms of a brain tumour
seizures (fits) persistently feeling sick (nausea), being sick (vomiting) and drowsiness. mental or behavioural changes, such as memory problems or changes in personality. progressive weakness or paralysis on one side of the body.
Conditions like epilepsy, stroke or Parkinson's disease can cause similar symptoms to brain tumors. And headaches are much more likely to be caused by something other than a brain tumor.

Arachnoid cysts can occur at different intracranial sites, including the cerebellopontine angle (CPA). They often occur in childhood, in the posterior fossa. They may present with symptoms such as dizziness, tinnitus and hearing loss, or they may be asymptomatic. Presentation with sudden deafness is very rare.
Ménière's disease is a disorder of the inner ear that causes severe dizziness (vertigo), ringing in the ears (tinnitus), hearing loss, and a feeling of fullness or congestion in the ear. Ménière's disease usually affects only one ear, but in 15% to 25% of people with the disorder, both ears may be affected.
Although tinnitus can improve with treatment, there is no known cure for the condition.
The symptoms of tinnitus can vary significantly from person to person. You may hear phantom sounds in one ear, in both ears, and in your head. The phantom sound may ring, buzz, roar, whistle, hum, click, hiss, or squeal. The sound may be soft or loud and may be low or high pitched.
Early brain tumor symptoms often involve headaches, nausea/vomiting (especially in the morning), vision changes (blurry, double), balance/coordination issues, weakness, and personality or cognitive shifts like memory problems, confusion, or mood swings, with seizures also being a common sign, though symptoms vary greatly by tumor location and size. If you experience persistent or concerning symptoms, see a doctor for proper evaluation, as these signs can also indicate other conditions.
These might include:
Diagnosing brain tumors. We sometimes find brain tumors when otherwise healthy people suddenly have a seizure, unusual weakness or speech problems. If you have these symptoms, go to an emergency room. If ER doctors suspect a brain tumor, they may send you to us for a full evaluation.
Experiencing non-existent foul smells and odours could be sign of cancer growing in the olfactory cortex or invading it from neighbouring tissues.
It's important to understand the connection between dizziness and brain tumors for early treatment. The cerebellum is key in balance, and tumors there can lead to balance issues. Vertigo can be a sign of a brain tumor, based on the tumor's spot.
Intracranial hypertension's clinical manifestations vary depending on the underlying cause, severity of pressure elevation, and individual patient factors. Common symptoms may include severe headaches, visual disturbances, nausea, vomiting, tinnitus, and, in severe cases, seizures or coma.
