Plain-English summary
A 6-year-old female crossbreed dog was brought in for worsening lameness in her right front leg over three months. The vet found muscle wasting and pain in her shoulder area. An MRI showed a large tumor near her shoulder, and a fine-needle biopsy confirmed it was a malignant peripheral nerve sheath tumor. Unfortunately, this type of tumor can be aggressive, and treatment options may vary based on the specific case. It's important for pet owners to discuss potential treatment plans with their veterinarian.

Abstract
This study describes a case of a six-year-old female crossbreed dog that had a three months history of progressive right thoracic limb lameness. Palpation revealed muscle atrophy of the scapular and humeral area and painfulness in this region. Magnetic resonance imaging was performed in T1- and T2-weighted and STIR (short inversion recovery) sequences in sagittal and transverse planes. The masses around the scapula and humerus were heterogeneously hyper-intense in STIR and measured about 9 cm. The tumour was heterogeneously iso-intense relatively to the surrounding tissues in T-2 weighted Gradient Echo and Spin Echo sequences. After MRI fine needle aspiration of a central part of the tumour was performed. The biopsy revealed multiple round cells with very little cytoplasm and fusiform cells in which the cytoplasm created protrusions. Cells were arranged in rows or formed a homogeneous cell mass. A malignant peripheral nerve sheath tumour was diagnosed cytologically.
