A 1-year-old female Boer goat was presented for necropsy following spontaneous death and history of acute recumbency, nystagmus, and sialorrhea. A swollen area was grossly observed in the brainstem at the level of the pons. On cut surface, the right cerebellar peduncles were expanded by a focal, pale, poorly demarcated, slightly depressed, and soft area of malacia. Microscopically, this area contained diffuse edema and necrosis, with microabscesses, neuronal necrosis, neuronophagia, axonal spheroids, vasculitis, and perivascular accumulations of lymphocytes, plasma cells, macrophages, and neutrophils. The diagnosis was based on the morphologic findings, fluorescent antibody test results, and special staining.
