Pseudochoreoathetosis is a rare movement disorder associated with loss of proprioception. Culprit lesions may occur at any point between the cerebral cortex and the peripheral nerve. Seldom is the underlying cause reversible or prone to improvement. An elderly man presented to our tertiary centre with choreoathetoid movements secondary to spondylotic subaxial cervical myelopathy. His myelopathy fulminated and he was emergently treated with posterior decompressive neurosurgery. Unexpectedly, his choreoathetoid movements improved significantly post-operatively. There are a multitude of reports of pseudochoreoathetosis secondary to lesions of various aetiologies; however, few have reported this disorder secondary to cervical spondylosis. To our knowledge, there is only one other report in the medical literature. Herein, we report a second case, for the purposes of raising awareness of this disorder, and to highlight relevant clinical pearls for clinicians who encounter this rare pathology.
假性手足徐动症是一种罕见的运动障碍，与本体感觉丧失有关。责任病灶可能发生在大脑皮层和外周神经之间的任何部位。潜在病因很少是可逆的或易于改善的。一位老年男性因颈椎病伴脊髓亚下颈椎病变出现舞蹈手足徐动症，到我们的三级中心就诊。他的脊髓病迅速恶化，并紧急接受后路减压神经外科治疗。出乎意料的是，他的舞蹈手足徐动症术后明显改善。有许多关于各种病因引起的假性手足徐动症的报告；然而，很少有报告称这种疾病是由颈椎病引起的。据我们所知，医学文献中只有另一个报告。在此，我们报告第二个病例，旨在提高对这种疾病的认识，并为遇到这种罕见病理的临床医生提供相关的临床要点。
