Bone wax used in neurosurgical procedures is a rare cause of complications after surgery. We present a patient who developed paraplegia following thoracic spine surgery. A subsequent MR imaging study demonstrated a signal void that resembled postoperative air but appeared to cause cord compression and proved after a second surgery to represent bone wax. Recognizing the MR imaging and CT characteristics of bone wax is important to prevent mistaking it for residual air in postoperative imaging.
神经外科手术中使用的骨蜡是手术后并发症的罕见原因。我们报告了一例胸椎手术后发生截瘫的患者。随后的磁共振成像(MR)研究显示了一个类似于术后空气的信号缺失,但似乎导致了脊髓压迫,并在第二次手术后证实为骨蜡。认识到骨蜡的 MR 成像和 CT 特征对于防止将其误认为术后影像学中的残余空气非常重要。
