Schwannoma (Neurilemoma) Symptoms & Causes

What causes schwannoma?    

The cause of schwannoma is unknown. These tumors sometimes occur in patients with von Recklinghausen disease (neurofibromatosis). 

What are the symptoms of schwannoma? 

Patients with tumors that affect nerves close to the surface of the body will likely discover a mass sooner than those with a tumor that affects a deep-seated nerve, which may grow large before it is discovered. The following are the most common symptoms of schwannoma. Keep in mind that patients may experience symptoms differently, depending on the location of the tumor. Symptoms include:

  • Painless or painful mass that is slow-growing
  • Electric like shock when affected area is felt (Tinel shock)

Usually no neurological problems or loss unless the tumor involves a major motor or sensory nerve or is compressed between the tumor and a rigid structure.

The symptoms of schwannoma may resemble those of other medical conditions. Always consult a physician for a diagnosis.
