【 摘 要 】

References(19)A Bengal tiger was presented for evaluation of weakness, ataxia and inappetance. Computedtomography (CT) and magnetic resonance imaging (MRI) revealed a mass extending from theT7-8 vertebral body to the left rib and compressing the spinal cord. On CT, the bonedestruction and sequestrum were shown. On MRI, the multilobulated mass appeared hypo- toisointense in T1-weighted and hyperintense in T2-weighted images. The tiger died afterimaging, most likely from renal failure. Chordoma without metastasis was diagnosed onnecropsy. The imaging characteristics were similar to those found in chordoma in humans.This report describes the use of CT and MRI in an exotic species.
