原发性骨恶性纤维组织细胞瘤的X线表现

The X-ray Findings of Primary Malignant Fibrous Histiocytoma of Bone

目的 :探讨原发性骨恶性纤维组织细胞瘤的X线表现。材料和方法 :回顾性分析 18例 (男 11例 ,女 7例。年龄16～ 71岁。)。经手术、病理证实的原发性骨恶性纤维组织细胞瘤的X线平片和CT表现。结果 :原发性骨恶性纤维组织细胞瘤好发于长骨干骺端或骨端。X线主要表现为溶骨性骨质破坏 ,部分病例呈膨胀性骨质破坏 ,软组织肿块或肿胀 ,骨膜反应少见 ,可合并病理性骨折。结论 :原发性骨恶性纤维组织细胞瘤X线表现缺乏特异性 ,但结合病史 ,在长骨干骺端或骨端溶骨性骨质破坏 ,无骨膜反应伴大的软组织肿块应考虑为原发性骨恶性纤维组织细胞瘤。

Purpose: To study the radiological features of primary malignant fibrous histiocytoma of bone. Materials and Methods: The plain film and CT data of 18 cases of primary malignant fibrous histiocytoma of bone confirmed by operation and pathology were retrospectively analysed. There were 11 males and 7 females aging from 16～71 years. Results: Most of the primary malignant fibrous histiocytomas of bone arose in the metaphyses or the ends of long bone. The tumor appeared as follows: osteolytic bone destruction or local expansive changes,soft tissue mass or swelling in some cases and it is rare for periosteal reaction, but pathological fracture were occasionally found. Conclusion: The X ray findings of primary malignant fibrous histiocytoma of bone are not specific, however, the osteolytic bone destruction arise in the metaphyses or the ends of long bone, with no periosteal reaction and large soft tissue mass, the diagnosis of primary malignant fibrous histiocytoma of bone should be also taken into consideration.
