Plain-English summary
A 12-year-old spayed female Labrador Retriever was found to have a malignant tumor on the right acoustic nerve after she suddenly developed severe neck pain and difficulty when opening her mouth. She also showed mild unsteadiness in her back legs. Unfortunately, the tumor was discovered during a necropsy, meaning she had already passed away. This case highlights the serious nature of tumors affecting the nervous system in dogs.

Abstract
A malignant schwannoma of the right acoustic nerve of a dog is described. The neoplasm was found during necropsy of a 12-year-old, spayed, female Labrador Retriever that experienced a sudden onset of severe pain in the neck and upon opening the mouth. Concurrent mild hind limb ataxia also was present. The tumor had infiltrative growth, and the spindle-shaped neoplastic cells were arranged in sheets and concentric whorls. Immunohistochemical staining of the neoplastic spindle cells was positive for S-100 antigen, neuron-specific enolase, and glial fibrillary acidic protein.
