BACKGROUND
Tumors of the cauda equina may shift with positioning on the operating table. Accurate localization at surgery is important to facilitate appropriate laminectomy and durotomy.
CASE DESCRIPTION
We report a case of a 28-year-old man with a schwannoma of the cauda equina at L4 on preoperative MRI. Intraoperative ultrasound revealed that the tumor had migrated cephalad, and was now located at L3.
CONCLUSION
Intraoperative ultrasound is a valuable technique in localization of tumors of the cauda equina.
背景
马尾神经肿瘤在手术台上的体位改变时可能会发生移位。手术中的准确定位对于进行适当的椎板切除术和硬脊膜切开术很重要。
病例描述
我们报告一例28岁男性，术前MRI显示L4水平马尾神经鞘瘤。术中超声显示肿瘤已向头侧移位，现位于L3水平。
结论
术中超声是定位马尾神经肿瘤的一种有价值的技术。
