Plain-English summary
A group of dogs with peripheral nerve sheath tumors, which can cause symptoms like limping and muscle wasting, were evaluated to understand their condition better. The most common signs included lameness in one front leg and loss of muscle mass. Diagnostic tests like myelography and electromyography helped identify the tumors, and surgery was performed to remove them. Unfortunately, the overall outlook for recovery after surgery is not very promising, with many dogs experiencing a return of the tumors or having shorter survival times, especially those with tumors near the spine.

Abstract
Fifty-one cases of canine peripheral nerve sheath tumors were reviewed. Signalment, presenting clinical signs, duration of clinical signs, physical and neurological examination findings, results of diagnostic procedures, type of surgery performed, tumor location, relapse-free intervals and survival times, and causes of death were evaluated. Tumors were divided into three anatomical groups: tumors involving nerves distal to the brachial or lumbosacral plexus (Peripheral Group), tumors involving nerves of the brachial or lumbosacral plexus (Plexus Group), and tumors involving the vertebral canal (Root Group). The most common clinical findings were unilateral forelimb lameness and muscle atrophy. The most useful diagnostic tests were myelography and electromyography. Although there was no significant difference, dogs in the Root Group tended to have shorter relapse-free intervals and survival times than dogs in the Plexus Group. The overall prognosis for surgical management of peripheral nerve sheath tumors is guarded to poor.
