title: Recurring tetraparesis attributable to a heartworm in the epidural space of a dog.
abstract: Recurring nonambulatory tetraparesis caused by a heartworm in the epidural space was diagnosed in a dog. On myelography and digital subtraction imaging, the parasite appeared as a large extradural mass. Surgical removal of a mature, female Dirofilaria immitis resulted in resolution of the neurologic signs.
