Abstract

An 8-year-old nongravid female llama with a 1-month history of progressive posterior paresis was referred because of suspected degenerative myelopathy secondary to copper deficiency or plant poisoning. Neurologic examination revealed loss of conscious proprioception and slightly depressed bilateral patellar reflexes. Electromyographic examination of hindlimb flexors and extensors did not elicit evidence of lower motor neuron disease. Possible fragmentation and mottling of the 10th thoracic vertebral body were noted radiographically. Results of a lumbar CSF tap, complete blood count, and fecal flotation were not diagnostic. In the face of poor prognosis, the llama was euthanatized. Postmortem and histologic evaluation revealed, in addition to disseminated visceral granulomas, an extradural pyogranulomatous mass comressing the cord laterally at the level of T-10. Large numbers of Coccidioides immitis were dispersed throughout the granulomas. Complement fixing antibody tests in 11 other herd members showed evidence of C immitis infection in three.
