    Abstract:
    Intraosseous occurrence of a spinal AVM is anecdotal, with only four such cases reported previously. This is the first report of a spinal intraosseous AVM in the cervical vertebrae. A 44-year-old male patient presented with a 2-month history of progressive quadriparesis and bladder dysfunction. Magnetic resonance imaging showed multiple flow voids within the C4 and C5 vertebral bodies, and an extradural component causing cord compression. CT showed extensive bony destruction at both levels. The diagnosis of an intraosseous AVM was confirmed with spinal angiography. The AVM was noted to be fed by branches from the ascending cervical arteries and the vertebral artery. The nidus was draining into the vertebral venous plexus and thence into the jugular vein through the marginal sinus. The patient underwent partial embolization of the AVM. Surgical resection was attempted but found to be unfeasible due to torrential bleeding. A 360-degree stabilization along with decompressive laminectomies was performed, resulting in clinical improvement and disease stabilization at one year follow-up. The case and its management dilemmas are discussed in light of a brief literature review.
