Abstract

A Bengal tiger was presented for evaluation of weakness, ataxia and inappetance. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a mass extending from the T7-8 vertebral body to the left rib and compressing the spinal cord. On CT, the bone destruction and sequestrum were shown. On MRI, the multilobulated mass appeared hypo- to isointense in T1-weighted and hyperintense in T2-weighted images. The tiger died after imaging, most likely from renal failure. Chordoma without metastasis was diagnosed on necropsy. 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.

摘要

一只孟加拉虎因虚弱、共济失调和食欲不振前来接受评估。计算机断层扫描（CT）和磁共振成像（MRI）显示一个肿块从T7 - 8椎体延伸至左肋骨并压迫脊髓。在CT上，显示出骨质破坏和死骨。在MRI上，多叶状肿块在T1加权像上呈低至等信号，在T2加权像上呈高信号。这只老虎在成像检查后死亡，最有可能死于肾衰竭。尸检诊断为无转移的脊索瘤。其影像学特征与人类脊索瘤相似。本报告描述了CT和MRI在一个外来物种中的应用。
