Schwannoma is a benign nerve sheath tumor most commonly located in the soft tissue. Occasionally, schwannomas involve osseous structures. The rarity of osseous involvement leads to omission of schwannoma from the initial differential diagnosis in the majority of cases. Intraosseous schwannomas arising in children have not been reported. We present the case of a schwannoma affecting the proximal tibial epiphysis in a growing child. Intraosseous schwannomas should be included in the differential diagnosis of lytic epiphyseal benign-appearing bone lesions in children. Its radiographic characteristics mimic those of benign chondroblastoma.
神经鞘瘤是一种最常见于软组织的良性神经鞘肿瘤。偶尔，神经鞘瘤会累及骨结构。骨受累情况罕见，导致在大多数病例的初始鉴别诊断中遗漏神经鞘瘤。儿童发生的骨内神经鞘瘤尚未见报道。我们报告一例生长中的儿童近端胫骨骨骺受神经鞘瘤影响的病例。骨内神经鞘瘤应纳入儿童溶骨性骨骺良性外观骨病变的鉴别诊断中。其影像学特征类似于良性软骨母细胞瘤。
