Multicentric osseous lymphoma with spinal extradural involvement in a dog

Area of Science:

• Veterinary Oncology
• Comparative Pathology
• Canine Neoplasia

Background:

• Multicentric osseous lymphoma is a rare condition in dogs.
• Early diagnosis and treatment are crucial for managing canine cancers.

Observation:

• A 7-year-old Siberian Husky presented with multicentric osseous lymphoma affecting the ribs and vertebrae.
• The dog experienced extradural spinal cord compression due to the lymphoma.

Findings:

• Surgical decompressive hemilaminectomy (L1-2) provided no improvement in neurological dysfunction.
• A combination of irradiation, chemotherapy, and surgical decompression achieved pain palliation.

Implications:

• This case highlights the challenges in treating aggressive canine lymphomas.
• Combined treatment modalities may offer palliative benefits for pain management in similar cases.
• Further research into novel therapeutic strategies for canine osseous lymphoma is warranted.
