What is Schwannoma?

Schwannomas are tumors that form in the nervous system from Schwann cells. They are also referred to as neurilemomas, neurolemomomas, or neuromas. They are frequently found on the nerve that connects the brain to the inner ear.  

Symptoms typically appear when the tumor has grown to the point where it puts pressure on the nerves nearby. Symptoms will change depending on the tumor’s location. Among the symptoms are:  

  • A noticeable lump  
  • Numbness  
  • Muscle deterioration  
  • Pins-and-needles sensation  
  • Back or neck pain at night.  
  • Aching, burning, or sharp pains caused by Schwannomas near the ear can impair hearing, balance or cause ringing sensations (tinnitus).  

Tumors of the facial nerve can cause facial paralysis or affect swallowing, eye movement, and taste sensations.  

What are the possible causes of schwannomas?

In most cases, the cause of schwannomas is unknown. They usually happen on their own. However, schwannomas can be caused by genetic disorders such as Carney complex, neurofibromatosis 2 (NF2), and schwannomatosis. 

How is the diagnosis of schwannomas made?

What are the treatments available for schwannomas?

What are the operations/ surgical treatments available for schwannomas?

Treatment for schwannoma may vary depending on the tumor’s location, the severity of symptoms, and whether the tumor is benign or malignant (cancerous). A benign schwannoma is treated with surgery to remove as much of the tumor as possible while leaving the affected nerve intact. Often, the entire tumor can be removed. 

A schwannoma is a type of nerve tumor that develops in the nerve sheath. In adults, it is the most frequent source of benign peripheral nerve tumors. However, it can appear at any age and in any part of your body. 

A schwannoma comes from a single bundle (fascicle) within the main nerve and disturbs the rest. When a schwannoma grows in size, it affects more fascicles, making removal more difficult. A schwannoma grows slowly overall. 

You may notice a pain-free lump if you develop a schwannoma in an arm or leg. Schwannomas are very seldom cancerous, but they can cause nerve damage and muscle weakness. If you notice any unusual lumps or numbness, consult Dr. Nitin Jagdhane, an expert brain, and spine specialist and a neurosurgeon in Mumbai.
