What Is Your Neurologic Diagnosis?

摘要

A1-year-old 15-kg (33-lb) female dwarf goat was evaluated because of a 1-month history of progressive neurologic disturbances. The goat lived in a rural environment with its dam and a few sheep and dogs. The owner had noticed neurologic signs 4 monthsearlier; at that time, the goat had received no treatment. Physical examination findings were considered normal. Because of repeated handling of the goat since birth, it was possible to perform a neurologicexamination as though the goat were a small ammai. Neurologic examination revealed that the goat had a depressed mental status, left head turn, wide-based stance, hypertonia, ataxia, hypermetria, and prolonged retention of food in the mouth. Postural reactions of all 4 limbs were diminished. Menace response was reduced bilaterally. Spinal reflexes were considered normal. Signs of pain were elicited during palpation of the cervical region of the vertebral column.
