Plain-English summary
An 11-year-old male Miniature Dachshund was brought in because he suddenly had trouble using his back legs. An MRI showed a mass pressing on his spinal cord, which was later identified as a type of cancer called hemangiosarcoma. The vet performed surgery to remove the mass, which helped relieve the pressure on the spinal cord. After the surgery, the dog was diagnosed with hemangiosarcoma, and the treatment aimed to improve his mobility and quality of life.

Abstract
An 11-year-old male Miniature Dachshund was referred for acute neurological deficits in the pelvic limbs. T2-weighted magnetic resonance imaging revealed that the spinal cord at the L1-2 intervertebral disc space was heterogeneously hyperintense in the sagittal plane and was mildly compressed from the ventral side by a small hypointense mass in the transverse plane. However, the lesion showed mass enhancement and severe spinal cord compression on post-contrast T1-weighted imaging. On three-dimensional myelography, a "golf tee sign" was observed around the mass. Therefore, we diagnosed an intradural extramedullary lesion. The mass was surgically removed and histologically diagnosed as a hemangiosarcoma. The "golf tee sign" observed on magnetic resonance myelography may be useful for distinguishing intradural extramedullary masses from intramedullary masses.
