“…One study described the morphometry of the lumbar internal vertebral venous plexus in dogs making use of CT angiography ( 25 ). A recent study describing the use of fast three-dimensional contrast-enhanced magnetic resonance angiography of the canine lumbar spinal cord vascular supply was unable to visualize most of the small vessels of the spinal cord, though none of the included dogs were diagnosed with vascular malformations or abnormalities ( 26 ). A study using CT angiography and 4-D magnetic resonance angiography showed that MRI allowed better identification of blood flow dynamics than CT angiography for the diagnosis of subclavian steal syndrome in a dog ( 27 ).…”

A 3.5-year-old male intact Staffordshire terrier crossbreed dog was presented with a one-week history of progressive paraparesis with fecal and urinary incontinence. Neurological examination was consistent with a T3-L3 myelopathy. A magnetic resonance imaging study revealed the presence of a well-circumscribed hemorrhagic space-occupying lesion at the level of T12, suspected to be a vascular malformation, such as cavernoma or arteriovenous fistula, primary hematoma or hamartoma; less likely considerations included hemorrhagic inflammation or hemorrhagic primary or secondary neoplasia. A dorsal laminectomy, durotomy, and midline dorsal myelotomy were performed with a surgical microscope, and the vascular lesion was identified and removed. Histological examination of surgical samples yielded fibrin, hemorrhage, hematoidin pigment, and some neural tissue. Although a lining wall was visualized during surgery consistent with a vascular malformation, there was no histological confirmation of such a structure, hampering definitive classification of the lesion. There was no gross or histopathological evidence that would support a diagnosis of a hamartoma or benign neoplasia. The dog was paraplegic with intact nociception the day following surgery. Ambulation was recovered within 2 weeks. Progressive and complete recovery of neurological function was seen over the next 12 weeks. No recurrence of neurological dysfunction was seen over a 12-month follow-up period. Surgical treatment should be considered in dogs with spinal intramedullary vascular lesions which can have a successful long-term outcome.
