Tarlov (perineural) cysts of the nerve root are common and usually incidental findings during magnetic resonance imaging (MRI) of the lumbosacral spine. There are a few case reports where symptomatic thoracic perineural cysts have been described in the literature. We report a case of a high thoracic nerve root perineural cyst that failed conservative therapy, requiring surgical intervention. Our patient presented with radicular symptoms involving the left hand. Imaging workup revealed a cystic lesion of the left T1 nerve root at the level of the foramen. Surgical resection resulted in significant improvement in patient symptoms, and pathology revealed a perineural cyst. We conclude that a thoracic perineural (Tarlov) cyst can be symptomatic by causing nerve root compression and can be mistaken as a nerve root sheath tumor on imaging. Surgical treatment can be curative.
神经根的塔尔洛夫（神经周）囊肿很常见，通常是腰骶椎磁共振成像（MRI）检查时的偶然发现。文献中有少数关于有症状的胸段神经周囊肿的病例报告。我们报告一例高位胸神经根神经周囊肿，保守治疗无效，需要手术干预。我们的患者表现为涉及左手的神经根症状。影像学检查发现椎间孔水平左侧T1神经根有一个囊性病变。手术切除使患者症状明显改善，病理显示为神经周囊肿。我们得出结论，胸段神经周（塔尔洛夫）囊肿可因压迫神经根而出现症状，在影像学上可能被误诊为神经根鞘瘤。手术治疗可治愈。
