An extradural spinal tumor was diagnosed in a 12-year-old Labrador retriever that was presented with a one-week history of paraparesis. Myelography indicated a deviation of the spinal cord to the right side at the level of the second lumbar (L2) vertebra. The difference in length measuring the left and right sides of the L2 vertebra suggested a fracture of the vertebral body. Severe bone remodeling and an extradural mass were seen on computed tomography (CT). Clinical, radiographical, and histological findings are described and considered homologous to extradural angiolipomas described in the human literature.
