AbstractA three-year-old crossbreed male dog was brought to the Neurology Unit because of an acute paraplegia. A clinical neurological examination indicated a spinal thoracolumbar syndrome evidenced by spastic paralysis of the hind limbs with no signs of deep pain sensation. Whereas the radiographic exams did not show any abnormality, cerebrospinal fluid changes indicated inflammation and hemorrhage. Serum titer for Toxoplasma gondii was 1:1024. The bacterial culture of the cerebrospinal fluid was negative. Since the animal did not improve with symptomatic treatment, it was euthanatized. The necropsy showed an extensive spinal hemorrhage from T8 to T11. Microscopic examination showed that paraplegia was due to the presence of an immature female Spirocerca lupi in the nervous tissue causing hemorrhagic myelomalacia.
