摘　　要：目的描述急性脊髓型减压病的MRI表现，提高对该病的认识水平。方法对5例有明确潜水作业史，且违反减压规定、快速出水后短时内出现完全或不完全性脊髓损害症状，以感觉障碍和大小便失禁为主要临床表现，经临床综合确诊为急性脊髓型减压病的患者的MRI表现进行回顾性分析。结果5例均见脊髓空泡征及T2WI弥漫性略高信号，在T1WI上呈等信号3例，略高信号和略低信号各1例。3例见猫头鹰眼征，2例见多发腔隙性病灶，T2WI脊髓内条状低信号及T1WI马尾略高信号各1例。结论急性脊髓型减压病的MRI表现具有一定特点，结合潜水并违规减压史和临床表现容易作出准确诊断。Objective To describe MR] findings of acute spinal cord decompression sickness. Methods MRI findings of 5 cases with clinical definite acute spinal cord decompression sickness were retrospectively analyzed. The main clinical informations included underwater performance history against regulations, short-term complete or incomplete spinal cord injury symptoms after fast going out of water, sensory disability and urinary and fecal incontinence, etc. Results Spinal cord vacuole sign was found in all 5 cases. Ise-signal intensity （ n = 3 ）, high signal intensity （ n = 1 ）, and low signal intensity （ n = 1 ） was demonstrated on T1WI, and high signal intensity （ n = 5 ） was found on T2WI. Owl eye sign was detected in 3 cases, and lacune foci were seen in 2 cases. Conclusion MRI findings of acute spinal cord decompression sickness had some characteristics, and it was easy to diagnose by combining diving history with clinical manifestations.
