目的探讨影像学在骨肿瘤与骨感染性病变中的鉴别诊断特点对比。方法本次选取四肢长骨感染、骨肿瘤患者各50例,均为我院2012年5月至2014年5月收治,回顾X线、MRI、CT表现。结果骨感染组股骨12例,占24%;胫骨17例,占34%;肱骨8例,占16%;尺骨5例,占10%;桡骨5例,占10%;腓骨3例,占6%。骨肿瘤组股骨14例,占28%;胫骨16例,占32%;肱骨8例,占16%;尺骨5例,占10%;桡骨4例,占8%;腓骨3例,占6%。两组骨质破坏累及骨骺、骨干髓腔改变、病变边界清晰可辨、骨膜新生骨、Codman三角、死骨形成、髓腔内肿瘤骨骼改变征象比较,差异有统计学意义(P<0.05)。结论应用影像学的多种手段,如DSA、X线平片、MRI、CT等,对各征象意义进行了解和充分运用,可用于骨肿瘤和骨感染性病变的鉴别诊断,以防降误诊率。
Objective To investigate the differential features of imaging in the differential diagnosis of bone tumors and bone lesions. Methods The selected long bones of limbs, bone tumors in patients with 50 cases, all of our hospital from May 2012 to May 2014 admitted to review X-ray, MRI, CT findings. Results There were 12 cases of femur in bone infection group (24%), 17 cases of tibia (34%), 8 cases of humerus (16%), 5 cases of ulna (10%), 5 cases of radius (10%), 3 cases of fibula %. There were 14 cases of femur in bone tumor group (28%), 16 cases of tibia (32%), 8 cases of humerus (16%), 5 cases of ulna (10%), 4 cases of radial bone (8%), 3 cases of fibula . There were significant differences between the two groups in the incidence of epiphyseal invasion, the change of the medullary cavity, the clear boundary of the lesion, the signs of periosteal neovascularization, Codman’s triangle, sequestrum formation and intramedullary neoplasm skeleton skeletal changes (P <0.05). Conclusions Various means of imaging such as DSA, X-ray, MRI and CT are used to understand and make full use of the meaning of each sign. It can be used in the differential diagnosis of bone tumor and bone-infecting lesion, .
