Summary
This case report details a young dog diagnosed with vertebral angiomatosis, a rare vascular disorder causing spinal cord compression. Surgical decompression provided temporary relief, highlighting the need for further understanding of this condition in canines.
Area of Science:
- Veterinary Neurology
- Comparative Pathology
- Canine Medicine
Background:
- Vertebral angiomatosis is a rare vasoproliferative disorder.
- It has been documented as a cause of myelopathy in felines.
- This condition has not been previously reported in canines.
Observation:
- A 3-year-old Cavalier King Charles spaniel presented with progressive ataxia and paraparesis.
- Computed tomography and magnetic resonance imaging revealed a T5 vertebral lesion with spinal cord compression.
- Histopathology confirmed vertebral angiomatosis.
Findings:
- Surgical decompression via T4-T5 hemi-dorsal laminectomy led to rapid initial improvement.
- Clinical signs recurred five months post-surgery, indicating potential for relapse.
- This case represents the first documented instance of vertebral angiomatosis in a dog.
Implications:
- This report expands the known host range for vertebral angiomatosis to include dogs.
- It underscores the importance of considering this rare vascular lesion in canine spinal disease.
- Further research is warranted to understand the pathogenesis and long-term management of canine vertebral angiomatosis.

01:54The Spinal Cord
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:16Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
