We present the MR findings in a case of tophaceous gout of the lumbar spine with cauda equina compression, mimicking an epidural abscess. The diagnosis was clinically unsuspected and confirmed at laminectomy. Tophus material in the paraspinal soft tissues appeared intermediate in signal intensity and showed heterogeneous contrast enhancement.
我们报告一例腰椎痛风石性痛风伴马尾神经受压的磁共振成像(MR)表现,其影像表现酷似硬膜外脓肿。临床诊断未考虑到此病,经椎板切除术后得以确诊。椎旁软组织内的痛风石物质在信号强度上呈中等水平,并表现出不均匀的对比增强。
