Clinical outcomes of traumatic brain injury dogs underwent CT or MRI

Three dogs (7-year-old, neutered male Chihuahua; case 1, 1-year-old, spayed female mixed breed; case 2, 10-month-old, female Maltese; case 3) were referred to Jeju Veterinary Medicine Teaching Hospital for traumatic brain injury.All three patients exhibited abnormal neurological symptoms.The patients were diagnosed through medical history obtained from their caregivers and through computed tomography (CT) or magnetic resonance imaging (MRI) scans.Structural brain abnormalities were observed in two dogs through CT scans and in one dog through MRI.Decompression therapy with mannitol was administered to all three dogs.Case 1, which showed CT findings of pulmonary hemorrhage but no significant brain injury, and case 2, which had mild brain damage on CT imaging, showed improvement in neurological symptoms and gait abnormalities after decompression therapy.However, case 3, which showed suspected brain hemorrhage and brain edema on MRI, did not respond to decompression therapy and was euthanized one month later.Imaging evaluation through CT or MRI in dogs with traumatic brain injury can assist clinical veterinarians in assessing the prognosis of patients.
