METHODS: In this illustrated case, a 34-year-old male patient presented with radicular pain due to nerve root compression. In the magnetic resonance imaging (MRI) examination of the spine, a synovial cyst was suspected, so the patient underwent no further examination before surgery. Intraoperatively, the authors were surprised to see a vascular malformation, which was shown to be an extradural arteriovenous fistula according to the histopathological examination.
CONCLUSIONS: In atypical MRI findings of the spine, vascular malformations should be considered. In cases with a spinal dural arteriovenous fistula, the thrombosis risk can be high and lead to a need for prolonged anticoagulation.
方法:在此示例中,一名34岁的男性患者因神经根受压而出现神经根疼痛。在脊柱的磁共振成像(MRI)检查中,怀疑有滑膜囊肿,所以病人在手术前没有接受进一步的检查。术中,作者惊讶地看到血管畸形,根据组织病理学检查显示为硬膜外动静脉瘘。
结论:在脊柱的非典型MRI发现中,应考虑血管畸形。在硬脑膜动静脉瘘的病例中,血栓形成的风险可能很高,并导致需要长期抗凝治疗。
