Can a brain tumor cause facial paralysis?
Facial paralysis that is due to a brain tumor usually develops slowly. Symptoms can include headaches, seizures, or hearing loss. In newborns, facial paralysis may be caused by trauma during birth.
Brain tumors in the posterior fossa of the skull, such as medulloblastomas, arise very close to the nucleus, or the origin, of the facial nerve in the brainstem. Compression in this area by such a tumor can cause complete facial paralysis.
It results from dysfunction of cranial nerve VII (facial nerve) which directs the muscles on one side of the face, including those that control eye blinking and closing and facial expressions such as smiling.
Weakness or numbness in the face, arms or legs.
The brain plays an important role in feeling sensations throughout the body. So brain tumors can cause numbness and tingling in the face, arms, hands, legs and feet.
Changes in judgment, including loss of initiative, sluggishness, and muscle weakness or paralysis is associated with a tumor in the frontal lobe of the cerebrum. Partial or complete loss of vision is caused by a tumor in the occipital lobe or temporal lobe of the cerebrum.
Facial paralysis is almost always caused by: Damage or swelling of the facial nerve, which carries signals from the brain to the muscles of the face. Damage to the area of the brain that sends signals to the muscles of the face.
Paralysis, often in the form of hemiplegia, can be a conspicuous consequence of brain cancer. While the paralysis is most profound just after the brain surgery, a certain return of motor power is common and may continue for several weeks or months.
It will largely depend on the type of tumor, but the most common symptoms of a facial tumor are pain, discomfort, displacement of facial features, and physical signs such as lumps and growth. Sometimes tumors can be felt just below the surface of the skin or on the bones.
Malignant and benign (non-cancerous) brain tumors have similar symptoms. They can cause seizures or cause neurologic problems, such as paralysis and speech difficulties.
Objective and importance: Facial paralysis and hemifacial spasm are rare presentations of aneurysms in the posterior fossa. We report an unusual case of rapidly progressive facial palsy caused by the acute expansion of an arteriovenous malformation-associated anteroinferior cerebellar artery aneurysm.
Can Bell's palsy be caused by a tumor?
Although rare, malignant tumors can also affect the facial nerve with similar presentation as Bell's palsy. Malignant peripheral nerve sheath tumor (MPNST) is an aggressive tumor with an annual incidence of 0.8 cases per 100,000 people.
Commonly used medications to treat Bell's palsy include: Corticosteroids, such as prednisone. These are powerful anti-inflammatory agents. If they can reduce the swelling of the facial nerve, the nerve will fit more comfortably within the bony corridor that surrounds it.
Usually, the first sign of a brain tumor is a headache, generally in conjunction with other symptoms.
In general, the most common symptoms of a brain tumor may include: Headaches. Seizures or convulsions. Difficulty thinking, speaking or finding words.
- 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.
- vision or speech problems.
Seizures are a common symptom of benign brain tumors and slow-growing cancers. Tumors can cause a part of the body to weaken or feel paralyzed. Hearing, sight and the sense of smell can be affected.
If the back part of the frontal lobe (which controls voluntary movements) is damaged, weakness or paralysis can result. Because each side of the brain controls movement of the opposite side of the body, damage to the left hemisphere causes weakness on the right side of the body, and vice versa.
Conditions that may mimic Bell's palsy include CNS neoplasms, stroke, HIV infection, multiple sclerosis, Guillain-Barré syndrome, Ramsay-Hunt syndrome, Melkersson-Rosenthal syndrome, Lyme disease, otitis media, cholesteatoma, sarcoidosis, trauma to the facial nerve, autoimmune diseases such as Sjogren's syndrome, and ...
Facial nerve damage
Medical experts believe that stress weakens the immune system and damages the seventh cranial nerve (or the facial nerve) which causes facial paralysis. The condition causes one side of your face to droop or become stiff.
Bell's palsy temporarily weakens or paralyzes facial muscles. A pinched facial nerve causes this paralysis, or palsy. People with this type of facial nerve palsy develop a droopy appearance on one — or sometimes both — sides of the face. The condition isn't serious and often resolves in a few months without treatment.
What are the early signs of facial paralysis?
- Rapid onset of mild weakness to total paralysis on one side of your face — occurring within hours to days.
- Facial droop and difficulty making facial expressions, such as closing your eye or smiling.
- Pain around the jaw or in or behind your ear on the affected side.
These symptoms include drowsiness, headaches, cognitive and personality changes, poor communication, seizures, delirium (confusion and difficulty thinking), focal neurological symptoms, and dysphagia. Some patients may have several of these symptoms, while others may have none.
Headaches, seizures and weakness throughout the body can all be potential brain tumor symptoms.
A blood test cannot diagnose a brain tumour. But some types of tumour release certain hormones or chemicals into the blood. If the tumour is affecting your pituitary gland or pineal gland, you may have blood tests to check for this.

Because growths on the face affect appearance, many people opt to have them removed. The process is relatively simple, and fortunately, the prognosis is generally excellent. Tumors are either benign or malignant. Benign facial tumors can grow larger, but most are not particularly life-threatening or dangerous.
Sarcoma of the head and neck is a type of cancer that begins in the connective tissues of the body, such as, bone (osteosarcoma), cartilage, (chondrosarcoma), skeletal muscle (rhabdomyosarcoma), smooth muscle (leiomyosarcomas), blood vessels (angiosarcoma), fat (liposarcoma) and neuroendocrine cells (Ewing sarcoma).
- new, persistent headaches.
- seizures (epileptic fits)
- persistent nausea, vomiting and drowsiness.
- mental or behavioural changes, such as changes in personality.
- weakness or paralysis, vision problems, or speech problems.
Imaging is used not only for local staging but also to differentiate between benign and malignant lesions. MRI is the preferred imaging modality for the evaluation of soft-tissue masses in clinical practice.
The symptoms can develop gradually over some months or even years if the tumour is slow growing. Or quickly over days or weeks if the tumour is fast growing.
What mimics a stroke with one sided facial paralysis?
Bell's palsy is a temporary paralysis of the facial muscles, causing drooping and weakness on one side of the face, and is sometimes mistaken for a stroke. While alarming, Bell's palsy is usually not permanent and resolves itself in two weeks to six months, depending on the severity.
In the majority of cases, facial paralysis from Bell's palsy is temporary. You're likely to notice gradual improvement after about two weeks. Within three months, most people have recovered full motion and function of their face. A delay in recovery is often accompanied by some form of abnormal facial function.
Bell's palsy is the most common form of facial paralysis in the United States, with approximately 15,000 to 40,000 cases a year.
- A facial nerve schwannoma is a growth made of Schwann cells which form part of the insulating sheath around the nerve.
- A facial nerve haemangioma is a growth made of blood vessels.
Osteoma is a benign tumor that often affects the maxillofacial region. It exhibits slow growth and remains asymptomatic for prolonged time and may cause facial asymmetry or functional disorders when it reaches vast proportions.
Bell's palsy is the most common cause of facial paralysis, although its exact cause is unknown. It results from dysfunction of cranial nerve VII, which connects your brain to the muscles that control facial expression (the nerve also is involved with taste and ear sensation).
Most people make a full recovery within 9 months, but it can take longer. In a small number of cases, the facial weakness can be permanent. Go back to see a GP if there are no signs of improvement after 3 weeks. Some cases might need to be treated with surgery.
- Inability to move one or both sides of the face.
- Reduced tearing.
- Facial drooping and/or weakness.
- Slurred speech.
- Altered sense of taste.
- Pain behind or in the ear.
- Difficulty drinking and/or eating.
Bell's palsy is not considered permanent, but in rare cases, it does not disappear. Currently, there is no known cure for Bell's palsy; however, recovery usually begins 2 weeks to 6 months from the onset of the symptoms. Most people with Bell's palsy recover full facial strength and expression.
Usually, the first sign of a brain tumor is a headache, generally in conjunction with other symptoms.
Can a brain tumor cause facial spasms?
Hemifacial spasm (HFS) is almost always induced by vascular compression but in some cases the cause of HFS are tumors at cerebellopontine angle (CPA) or vascular malformations.
Changes in personality or behavior. Weakness, numbness, or loss of movement in one part or one side of the body. Difficulty with balance or dizziness. Sensory changes like difficulty hearing, difficulty seeing, or loss of smell.
- A headache that changes depending on the time of day and position of the head and gets worse over time.
Although rare, malignant tumors can also affect the facial nerve with similar presentation as Bell's palsy.
Multiple sclerosis and skull base tumors can also damage the nerve insulation and cause trigeminal neuralgia. This damage to the insulation results in severe, stabbing, electric shock like pain in the face, coursing along the nerve.
- Alzheimer's disease.
- Headaches or migraines.
- Lyme disease.
- Multiple Sclerosis.
- Subdural hematoma.
A regular, routine eye test can sometimes detect eye problems that indicate the presence of a brain tumour before any symptoms become obvious. An eye test is particularly good at identifying any swelling of the optic disc (a condition called papilloedema) and can also identify when there is pressure on the optic nerve.
When a person is diagnosed with a brain tumor, changes in behavior and thinking occur in most patients at some point during their treatment. Changes in behavior may include mild memory loss, mood swings, or intense emotional outbursts.
