Plain-English summary
A 9-year-old male mixed breed dog was brought in for worsening limping on his left front leg over the past two months. Tests showed nerve damage in the muscles of that leg, and imaging revealed a large mass near the upper arm bone that was affecting nearby nerves. Although a needle test didn't provide clear results, a biopsy confirmed it was a malignant peripheral nerve sheath tumor. The dog’s treatment plan would depend on the veterinarian's recommendations based on the diagnosis.

Abstract
A 9-year-old male neutered mixed breed dog had a two-month history of progressive left thoracic limb lameness. There was electromyographic evidence of denervation potentials in all muscles of this limb. In magnetic resonance images a multilobulated, hyperintense mass was visible caudal to the middiaphysis of the left humerus on T-2 weighted images. The mass, which was isointense with surrounding tissue on T1 weighted images, extended proximally towards the brachial plexus. The mass was also visible as a fusiform structure of mixed echogenicity sonographically, although fine-needle aspiration performed at this time was nondiagnostic. A malignant peripheral nerve sheath tumor was diagnosed histopathologically.
