Radiofrequency ablation (RFA) is an effective treatment that has occasionally been associated with transient paresthesias. This case report details an unusual presentation of paresthesias after lumbar medial branch RFA. A 48-year-old female patient reported pain, numbness, and swelling on the left buttock and posterolateral thigh. A physical exam revealed allodynia over the left posterolateral thigh without neurologic deficits two weeks after RFA of the left-sided lumbar medial branch nerves innervating the L4-L5 and L5-S1 facet joints. Shortly after the RFA of the contralateral targets, the patient complained of numbness of the right-sided lower back extending laterally from the right hip to the right knee. Imaging confirmed the appropriate placement of all needles in both procedures. Both instances of paresthesias resolved over time. This case report aims to demonstrate that RFA can be associated with unusual paresthesias and that these adverse effects do not warrant excessive workup.
射频消融术（RFA）是一种有效的治疗方法，偶尔会伴有短暂性感觉异常。本病例报告详细介绍了腰椎内侧支射频消融术后感觉异常的不寻常表现。一名48岁女性患者报告左侧臀部和大腿后外侧疼痛、麻木和肿胀。体格检查发现，在对支配L4-L5和L5-S1小关节的左侧腰椎内侧支神经进行射频消融术后两周，左侧大腿后外侧存在痛觉过敏，但无神经功能缺损。在对侧靶点进行射频消融术后不久，患者抱怨右侧下背部麻木，从右臀部向外侧延伸至右膝。影像学检查证实两次手术中所有针的放置位置均正确。两次感觉异常均随时间逐渐缓解。本病例报告旨在证明射频消融术可能与不寻常的感觉异常有关，且这些不良反应无需进行过多检查。
