目的 探讨放射性颌骨骨肉瘤的CT影像学表现.方法 回顾性分析13例放射性颌骨骨肉瘤患者的临床流行病学及CT影像学表现.观察项目:病变部位、骨质破坏、瘤骨、骨膜反应、软组织肿块及钙化.13例中男性12例,女性1例;发病年龄29~ 68岁,中位年龄48岁;部位:下颌骨8例,上颌骨5例.所有患者均行肿瘤切除术.结果 放射性骨肉瘤发生于放疗后3.5 ~14.0年(平均11年).影像学分型:8例成骨型、1例溶骨型、4例混合型病灶.12例病灶内见肿瘤骨,11例见骨膜反应.12例病灶内见软组织肿块自骨质破坏区向外侵犯.结论 放射性颌骨骨肉瘤的CT影像学特征性表现为放疗后原照射野内出现骨破坏,并伴大量的瘤骨形成和显著的软组织肿块,为临床诊断及术前评估提供重要依据.
目的 探討放射性頜骨骨肉瘤的CT影像學錶現.方法 迴顧性分析13例放射性頜骨骨肉瘤患者的臨床流行病學及CT影像學錶現.觀察項目:病變部位、骨質破壞、瘤骨、骨膜反應、軟組織腫塊及鈣化.13例中男性12例,女性1例;髮病年齡29~ 68歲,中位年齡48歲;部位:下頜骨8例,上頜骨5例.所有患者均行腫瘤切除術.結果 放射性骨肉瘤髮生于放療後3.5 ~14.0年(平均11年).影像學分型:8例成骨型、1例溶骨型、4例混閤型病竈.12例病竈內見腫瘤骨,11例見骨膜反應.12例病竈內見軟組織腫塊自骨質破壞區嚮外侵犯.結論 放射性頜骨骨肉瘤的CT影像學特徵性錶現為放療後原照射野內齣現骨破壞,併伴大量的瘤骨形成和顯著的軟組織腫塊,為臨床診斷及術前評估提供重要依據.

Objective To evaluate the CT features of radiation-induced jaw osteosarcoma(RIJOS) developed after therapeutic irradiation for a variety of nonosseous lesions.Methods The demographic and CT findings of thirteen patients with RIJOS were reviewed retrospectively.Observation items included location,bone destruction,mineralized tumor matrix,periosteal reaction,soft tissue extension and calcification.Of the thirteen patients,twelve were male and one was female.The mean age was 48 years (range:29-68 years).Five patients had tumors in the maxilla and eight in the mandible.All the patients underwent tumor resection.Results The latent period before development of RIJOS ranged from 3.5 to 14 years (mean,11 years).In all thirteen patients,eight tumors were osteoblastic,with one osteolytic and four mixed lesions.Osteoid tumor matrix mineralization was present in twelve patients.Periosteal reaction was identified in 11 cases.Soft-tissue extension was present in all patients beyond the area of bone destruction.Conclusions The characteristic CT imaging of RIJOS showed the bone destruction associated with a large number of mineralized tumor matrix and significant soft tissue extension in the original radiation field after radiotherapy.CT findings could play an important role in identifying the tumor and pre-operative assessment.
