目的探讨儿童骨良性纤维组织细胞瘤(benign fibrous histiocytoma,BFH)的临床及影像诊断。方法回顾性分析7例儿童BFH的临床及影像资料。结果 3例BFH发生在股骨干骺端,3例在胫骨干骺端,1例生在肱骨,临床上患者以局部疼痛为主,持续数月甚至数年(平均5个月),大部分患者疼痛同病理性骨折没有联系,影像上病灶呈分叶状溶骨性破坏,其内可见骨性分隔,边缘大部分有厚薄不一的硬化边,或没有硬化边,本组病例均位于长骨干骺端,均局限于骨内,无骨膜反应及软组织肿块,1例术后复发。结论 20岁以下BFH患者可能被低估了。儿童及青少年患者影像表现类似但有别于非骨化性纤维瘤伴不可解释的疼痛应该考虑为骨BFH。
Objective To investigate the clinical and imaging diagnosis of benign fibrous histiocytoma (BFH) in children. Methods The clinical and imaging data of 7 children with BFH were retrospectively analyzed. Results Three cases of BFH occurred in the metaphyseal femur, three cases in the metaphysis of the tibia, one in the humerus, and the majority of patients were clinically localized pain for several months or even years (average 5 months) Pain with pathological fractures are not linked, the image lesions were lobulated osteolytic destruction, which can be seen within the bony separation, the edge of most of the thickness of the sclerosis, or no sclerosis, this group of patients are located in the long trunk Metaphyseal end, are confined to the bone, no periosteal reaction and soft tissue mass, 1 case of recurrence. Conclusions BFH patients under the age of 20 may be underestimated. Children and adolescents with similar imaging performance but different from non-ossifying fibroma with unexplained pain should be considered as bone BFH.
