Pigmented villonodular synovitis (PVNS) is a benign proliferative disorder primarily occurring in the large joints of the appendicular skeleton such as the knee and hip joints. We present an unusual case of PVNS involving the cervical spine in an adult. MR imaging showed an enhancing mass lesion arising from the posterior elements of the cervical spine and hyperintensity on the T2-weighted images, without evidence of T2 susceptibility effects. Gross total excision of the tumor was performed, and the diagnosis was established by histopathology.
色素沉着绒毛结节性滑膜炎（PVNS）是一种主要发生于四肢骨骼大关节（如膝关节和髋关节）的良性增殖性疾病。我们报告一例罕见的成年患者PVNS累及颈椎的病例。磁共振成像显示颈椎后部结构出现强化肿块，T2加权像呈高信号，无T2*敏感效应。对肿瘤进行了全切除，通过组织病理学确诊。
