RESUMO
Computed tomography was used to aid in the antemortem diagnosis of leukoencephalomyelitis in a goat infected by caprine arthritis encephalitis virus (CAEV). Imaging results were corroborated by histologic examination. This report discusses various methods of imaging the nervous system and their potential for use in the antemortem diagnosis of CAEV neurologic changes.
Résultats d'une tomodensitométrie chez une chèvre cachemire de l'Australie(Capra hircus)âgée de 5 ans souffrant d'une lymphoencéphalomyélite en raison du virus de l'arthrite caprine. La tomodensitométrie a été utilisée pour faciliter le diagnostic antemortem de la lymphoencéphalomyélite chez une chèvre infectée par le virus de l'arthrite-encéphalite caprine (VAE). Les résultats de l'imagerie ont été corroborés par l'examen histologique. Ce rapport discute les diverses méthodes d'imagerie du système nerveux et leur utilisation potentielle pour le diagnostic antemortem des changements neurologiques du VAE.(Traduit par Isabelle Vallières).

A 2-yr-old male intact alpaca (Vicugna pacos) was admitted for a 4-day history of anorexia and colic. Five months prior, the alpaca had undergone surgical removal of a duodenal trichophytobezoar and had recovered uneventfully. The alpaca died under anesthesia, and diaphragmatic herniation of the third gastric compartment (C3) was diagnosed at necropsy. A defect was identified in the left dorsal hemidiaphragm accompanied by herniation of 80% of C3 and the aboral portion of the second gastric compartment into the pericardial sac. The smooth margins and dorsal location of the diaphragmatic defect suggested a congenital origin. Diaphragmatic herniation is uncommon in camelids, and only one other case has been reported. Due to the dorsal location of the diaphragmatic defect in this animal, positioning during the previous surgery may have initiated a partial entrapment of gastric compartments, leading to a more complete incarceration between when the animal was discharged and presented again.
