Plain-English summary
A 2-year-old crossbreed dog was brought in because it had been having trouble walking for six weeks, showing weakness in its back legs. Imaging tests revealed abnormal blood vessels in the spinal cord, which were causing swelling and bleeding in that area. A biopsy confirmed that the dog had an arteriovenous malformation, a type of blood vessel issue in the spinal cord. Treatment details were not specified, but addressing this condition typically involves surgery or other interventions to manage symptoms and improve mobility.

Abstract
A 2-year-old crossbreed dog was presented for evaluation of a 6-week history of progressive paraparesis. Magnetic resonance imaging and computed tomography angiography of the thoracic and lumbar spinal cord disclosed multifocal, anomalous, small, vascular structures, distributed throughout the subarachnoid space of the included section of the spinal cord. An additional focal intramedullary lesion was identified extending from T9 to T10 to T12. Histopathological examination confirmed the presence of an intramedullary arteriovenous malformation affecting the thoracic spinal cord and leading to diffuse congestion and focal hemorrhages into the affected spinal cord.
