Acute transverse myelitis (ATM) rarely involves the cervical spinal cord. We report on two patients with ATM and cervical cord involvement. Magnetic resonance imaging (MRI) revealed high intensity signals in T2 extending far beyond the sensory level in both patients. Motor evoked potential (MEP) was unrecordable in all but one limb, and there it was marginally prolonged. Tibial somatosensory evoked potential (SEP) was unrecordable while median SEP was normal in both patients. Both MEP and SEP correlated with their respective clinical deficits but MEP seemed to correlate better with the MRI changes.
急性横贯性脊髓炎（ATM）很少累及颈髓。我们报告了两例ATM累及颈髓的患者。磁共振成像（MRI）显示，两名患者的T2加权像上均有高强度信号，其范围远远超出感觉平面。除一个肢体外，所有肢体的运动诱发电位（MEP）均无法记录，该肢体的MEP稍有延长。两名患者的胫神经体感诱发电位（SEP）均无法记录，而正中神经SEP正常。MEP和SEP均与各自的临床缺陷相关，但MEP似乎与MRI变化的相关性更好。
