Thalamic pain syndrome is classically described as chronic pain after an infarct of the thalamus. It leads to a decrease in the quality of life, especially for patients with inadequate treatment. Supportive imaging, such as a thalamic lesion or infarct, is widely accepted as necessary to diagnose this condition.
In this case report, we describe the case of a patient who developed allodynia and hyperesthesia with a hemibody distribution characteristic of thalamic pain syndrome, despite having no clear inciting event or identifiable thalamic lesion. This patient was successfully treated with cervical and thoracic spinal cord stimulation (SCS).
We suggest that this patient may have presented with a non-lesional thalamic pain syndrome, supported by the classic hemibody allodynia and hyperesthesia and the response to SCS. Further, we demonstrate that SCS was an effective method to control this central pain disorder.
丘脑痛综合征通常被描述为丘脑梗死发作后的慢性疼痛。它会导致生活质量下降，尤其是对于治疗不充分的患者。诸如丘脑病变或梗死等支持性影像学检查被广泛认为是诊断该病症的必要条件。
在本病例报告中，我们描述了一名患者的病例，该患者出现了具有丘脑痛综合征特征的半身分布的感觉异常和感觉过敏，尽管没有明确的诱发事件或可识别的丘脑病变。该患者通过颈胸脊髓刺激（SCS）成功得到治疗。
我们认为该患者可能表现为非损伤性丘脑痛综合征，依据是典型的半身感觉异常和感觉过敏以及对脊髓刺激的反应。此外，我们证明脊髓刺激是控制这种中枢性疼痛障碍的有效方法。
