神经鞘瘤是来源于神经鞘瘤细胞(或施万细胞)的单发的高分化的良性肿瘤。神经鞘瘤在软组织肿瘤常见,但发生于骨骼少见,发病率不足骨肿瘤的0.2%[1,2],其主要来源于骨膜的小神经分支或伴随骨营养血管的小神经分支,来源于骨神经者很少见,发生部位较多。发病年龄一般为2.5～65岁,但 Schwannomas are single, well-differentiated benign tumors derived from Schwannoma cells (or Schwann cells). Schwannomas are common in soft tissue tumors, but occur in rare bones, with less than 0.2% incidence of bone tumors [1, 2], which are mainly derived from the small nerve branches of the periosteum or the small nerve branches associated with the bone nutrient vessels, Nerves are rare, more sites occur. Age of onset is generally 2.5 to 65 years old, however
