An MR study performed on a patient who presented a tetraplegia after liver transplantation, revealed bilateral hypersignal of internal globus pallidus on T2 weighted images. Diagnosis of extrapontine myelinolysis was proposed based on clinical presentation and lesions topography, although absence of natremic disorders. Confirmation of diagnosis was obtained on an MR study performed a month later, which demonstrated a pontine extension. Extrapontine myelinolysis can precede pontine involvement. Diagnosis of myelinolysis should be evoked although MR normal appearance of the pons.
对一名肝移植后出现四肢瘫痪的患者进行的一项磁共振成像（MR）研究显示，在T2加权图像上双侧苍白球内侧呈高信号。尽管没有血钠紊乱，但根据临床表现和病变部位，提出了桥外髓鞘溶解症的诊断。一个月后进行的MR研究证实了诊断，该研究显示病变延伸至脑桥。桥外髓鞘溶解症可先于脑桥受累出现。尽管脑桥的MR表现正常，也应考虑髓鞘溶解症的诊断。
