![]() Nerve Sheath Tumor in DogsSchwannoma in Dogs
Schwannomas are tumors that originate in the myelin sheath. The myelin sheath is produced by the Schwann cell, a specialized cell which surrounds the peripheral nerves, providing mechanical and physical support for the nerves as well as insulating the nerves that transmit the nervous system’s electrical signals. The peripheral nervous system consists of the nerves outside of the central nervous system (brain and spine). Peripheral nerve sheath tumor is the term that has been proposed to include schwannomas, neurofibromas (nerve fiber tumors), neurofibrosarcomas (malignant nerve fiber tumors), and hemangiopericytoma (tumor of blood vessels and soft tissue), since they are all believed to arise from the same cell type.

Causes
Diagnosis
Your veterinarian will perform a complete physical exam on your dog, including a blood chemical profile, a complete blood count, a urinalysis and an electrolyte panel. You will need to provide a thorough history of your dog's health leading up to the onset of symptoms. A computed tomography (CT) or, ideally, a magnetic resonance imaging (MRI) can provide the most information regarding the extent and location of the disease. An electromyogram (a measurement of muscle activity) will show abnormal muscle activity if there is a schwannoma present.
