摘　　要：目的　探讨骨韧带样纤维瘤的临床与X线特点。方法　回顾性分析经手术病理证实的 6例骨韧带样纤维瘤的临床及X线表现。结果　 6例病变位于股骨 2例 ,胫骨 2例 ,桡骨 1例 ,肱骨 1例。骨质呈囊状膨胀性改变 ,内见粗细不等骨小梁影 6例 ,伴有骨嵴 3例 ,边缘不同程度硬化 6例 ,软组织肿胀 4例 ,未见钙化和骨膜反应。结论　长骨干骺端为好发部位 ,以骨内具有骨小梁结构的囊状膨胀性改变 ,瘤壁硬化 ,无钙化及骨膜反应是该病的主要X线表现 ,而“根须”Objective To explore the clinical and radiological findings of skeletal desmoplastic fibromas.Methods Radiographs of six patients with desmoplastic fibromas proved by pathology were retrospectively reviewed.Results Two tumors arose in femur,two in tibia,one in radius and one in humur.In plain radiography,these lesions were always metaphyseal and expansile lytic with a reactive bony rim(n=6).They often had a trabeculated or honeycomb appearance into lesion and four tumors invaded adjacent soft tissue.Conclusion Desmoplastic fibromas of long bones are nearly always metaphyseal.Radiographs disclose a expansile lytic lesion with a sclerotic rim and a trabeculated apperance into it.And the 'root hair'sign is fairly characteristic for this tumor.No calcification and periosteal reaction can be seen.
