Type 2 (NF2) Much less common, causing hearing loss, ringing in the ears, and balance problems

It can cause problems with hearing and balance, and also ringing in the ears (tinnitus). About 7 out of every 100 acoustic neuromas are caused by neurofibromatosis type 2 (NF2). Tinnitus is a common symptom and not a disease in itself. It can depend on things such as how big the tumour is, how much damage has been caused and how difficult treatment was. The most common tumors associated with neurofibromatosis type 2 are called vestibular schwannomas or acoustic neuromas. Mutations in the NF2 gene cause neurofibromatosis type 2. The resources on this site should not be used as a substitute for professional medical care or advice. Neurofibromatosis 2 (NF2) is much less common than NF1. Signs and symptoms of NF2 usually result from the development of benign, slow-growing tumors (acoustic neuromas) in both ears. Gradual hearing loss; Ringing in the ears; Poor balance; Headaches.

Type 2 (NF2) Much less common, causing hearing loss, ringing in the ears, and balance problems 2Neurofibromatosis type 2 (NF2) is much less common than NF1, affecting about 1 in 25,000 people worldwide regardless of sex or ethnicity. NF2 can also cause schwannomas to develop on other cranial or peripheral nerves as well as other tumors such as meningiomas (tumors of the membranes surround the brain and spinal cord) and ependymomas (tumors that develop from cells that line the ventricles of the brain and center of the spinal cord). Neurofibromatosis 2 (NF2) is a disorder that causes tumors to form on nerves in the brain and spinal cord. When a tumor forms on this nerve, it may cause hearing loss, vision impairment, and problems with balance. Neurofibromatosis type 1 (NF1) is more common than neurofibromatosis type 2 (NF2). A sudden hearing loss occurs in about 25 of patients with acoustic neuroma. Tinnitus is very common in acoustic neuroma, and is usually unilateral and confined to the affected ear. It has been estimated that 5 of persons with sensorineural hearing loss have acoustics (Daniels et al 2000), but this estimate is suspect as it would imply a much higher prevalence of acoustic neuromas than are commonly accepted. Acoustic neuroma caused by neurofibromatosis type II (NF 2) should be suspected in young patients and those with a family history of neural tumors.

In contrast to neurofibromatosis type 1 (NF1), NF2 produces a paucity of cutaneous manifestations. Hearing loss, ringing in the ears, and balance problems associated with vestibular nerve lesions. Prenatal testing may not be possible if the affected parent is the first affected person in the family and a mutation cannot be found. Unlike vestibular lesions, intracranial meningiomas may be quite slow growing; surgical resection should be considered only when such lesions are causing serious, disabling symptoms. Less commonly, acoustic neuromas may cause sudden hearing loss. Acoustic neuromas are the most common of these tumors and often occur in both ears by age 30. Almost all individuals with NF2 develop tumors on both nerves to the ears (also called the eighth cranial nerve). These peripheral schwannomas rarely cause neurological symptoms, but they may rub on clothing or be cosmetically disfiguring.

Neurofibromatosis Type 2: Practice Essentials, Background, Etiology

Type 2 (NF2) Much less common, causing hearing loss, ringing in the ears, and balance problems 3Over time the tumor can cause gradual hearing loss, ringing in the ear, and dizziness. As the tumor expands into the cerebellopontine angle, hearing loss may worsen, facial weakness may occur, and balance problems (disequilibrium) may occur. Surgical removal is the most common treatment for acoustic neuromas, especially large ones. Acoustic neuromas cause hearing loss, ringing in the ears, dizziness, and a variety of other symptoms. The tumor capsule adherent to the delicate facial nerve is not removed. Balance problems are common and generally improve after surgery with head exercises, Pilates, or Tai Chi. An acoustic neuroma is not cancerous (malignant); it does not spread to other parts of the body. Hearing loss may be accompanied by ringing in the ears, a condition known as tinnitus, or by a feeling of fullness in the affected ear. Acoustic neuromas can also cause dizziness and problems with balance such as unsteadiness. In a small subset of cases, acoustic neuromas occur as part of a rare disorder known as neurofibromatosis type II. Tinnitus is very common in acoustic neuroma, is usually unilateral and confined to the affected ear. All in all, CT’s are a much less satisfactory situation than when one has the option of using an MRI. Neurofibromatosis (NF) is a genetic neurological disorder that can affect the brain, spinal cord, nerves and skin. NF1, formerly known as von Recklinghausen’s NF, is the more common of the types. The rare form of NF, schwannomatosis, which was recently identified, does not develop on the eighth cranial nerves, and does not cause hearing loss. Though schwannomatosis may also lead to numbness, weakness or balance problems like NF1 or NF2, the symptoms are less severe. Untreated, acoustic neuromas can create serious neurological problems and even become life-threatening. Acoustic neuromas large enough to cause these symptoms are rare, occurring in only 1 out of 100,000 people per year. Early symptoms include hearing loss, ringing in the ear (tinnitus), and dizziness. These are called NF2 (neurofibromatosis type 2) tumors.

Neurofibromatosis Type 2: Practice Essentials, Background, Etiology

The separate subsection heading implies this is a common or prominent symptom, when it is not. Larger tumors can press on the trigeminal nerve (CN V), causing facial numbness and tingling – constantly or intermittently. Type 2 (NF2) which can lead to acoustic neuroma formation in some people, most acoustic neuromas occur spontaneously without any evidence of family history (95 ). However, symptoms have been known to develop in children as well as much older adults. Neurofibromatosis Type 2 (NF2) is a genetic disorder in which tumors called schwannomas are found on nerves in the inner ear. The most common early symptoms are hearing loss, ringing in the ears (tinnitus), and loss of balance caused by tumors growing on the nerve from the ear to the brain. Neurofibromatosis type 2 is far less common than neurofibromatosis1 affecting about 1 in 40,000 births. Type 1 neurofibromatosis (Nf1) – or von Recklinghausen’s disease, von Recklinghausen NF, or peripheral neurofibromatosis. Patients do not develop the neurofibromas seen in Nf1 and Nf2. Neurofibromatosis is the most common genetic neurological disorder that is caused by a single gene.

Neurofibromatosis Type 1 is the more common form of the disease, occurring in 1 in 3,000 to 4,000 births. In addition, NF1 can cause orthopaedic problems, including bone abnormalities. Neurofibromatosis Type 2 is less common, occurring in 1 in 25,000 to 40,000 births. NF2 mostly affects the central nervous system, causing tumors of the brain and spinal cord. Neurofibromatosis (NF) is nervous system disease that causes skin defects and tumors on nerve tissues. The most common type of tumor is called a neurofibroma. Early symptoms usually involve hearing and balance problems. Ringing in the ears. Providing specialized care for your ear, hearing and balance needs through advanced treatment and technology. Hearing loss is a common problem caused by many factors including heredity, noise exposure and aging. Neurofibromatosis type 2 (NF2) is a genetic disorder of the nervous system that causes tumors to grow on nerves of the brain and spine. Symptoms can include ringing in the ears (tinnitus) and vertigo. Neurofibromatosis is a genetic disorder of the nervous system. Type 2 (NF2) Much less common, causing hearing loss, ringing in the ears, and balance problems; can also lead to cataracts or numbness or weakness in the arms or legs; often starts in the late teen or early adult years Schwannomatosis The rarest type, which causes intense, chronic pain in any part of the body, generally affecting people in their 20s and 30s; possible development of tumors in the cranial, spinal, and peripheral nerves, but not affecting the nerve that controls hearing and balance. Meniere’s disease is an inner ear disorder characterized by pressure and fullness in the ear and episodes of vertigo, a spinning sensation. It can cause problems with hearing and balance, and also ringing in the ears (tinnitus). About 7 out of every 100 acoustic neuromas are caused by neurofibromatosis type 2 (NF2). Tinnitus is a common symptom and not a disease in itself.
