Abstract

Subarachnoid extramedullary intraspinal ‘cysts’ containing cerebrospinal fluid (CSF), known as ‘diverticula’, can occur due to chronic inflammation or trauma in human beings and veterinary species. In dogs, these diverticula typically occur in the dorsal subarachnoid space at the level of the first and third cervical vertebrae of young, large breed dogs, or at the level of the caudal thoracic vertebrae of older, medium and small breed dogs. We present a case of a seven-year-old female neutered flat-coated retriever which experienced clinical signs localised to the cauda equina. Myelography and computed radiography (CT) imaging demonstrated a subarachnoid diverticulum in the ventral subarachnoid space at the level of the seventh lumbar vertebra (L7) cranial to a spinal sarcoma.
