We report the case of a 17-year-old boy with a soft tissue aneurysmal bone cyst(STABC) located in the posterior aspect of the right mandible.Conventional radiography revealed no positive findings.On the computed tomography scan,the lesion appeared to have a nonuniform intralesional density.Magnetic resonance imaging revealed an abnormal soft tissue masses with cystic component in the superficial part of right mandibular body and angle with intact cortex.Following histopathological examination,fibro-histiocytic proliferation,blood-filled spaces and multinucleated giant cells were seen and the lesion was diagnosed as a STABC.The mass together with underlying bone and periosteum on its periphery was surgically resected under general anesthesia.Thirty-six months after surgery the patient was assessed at outpatient clinic and found no sign of recurrence This may be only the first reported case of the mandible in the English literature of this extremely rare benign tumor occurring in soft tissue. 展开更多

目的探讨201Tl显像在骨与软组织病变定性诊断中的临床价值。方法对58例骨骼肌肉系统良、恶性病变进行201Tl显像,分别以注射后5min(早期)和2h(延迟期)显像,同时应用肉眼分析和半定量分析。其中6例骨肉瘤病例接受术前新辅助化疗前后均行20... 目的探讨201Tl显像在骨与软组织病变定性诊断中的临床价值。方法对58例骨骼肌肉系统良、恶性病变进行201Tl显像,分别以注射后5min(早期)和2h(延迟期)显像,同时应用肉眼分析和半定量分析。其中6例骨肉瘤病例接受术前新辅助化疗前后均行201Tl定量显像,计算变化率(AR)并与肿瘤坏死率(TNR)进行对照研究。对其中43例骨病变病例与同期进行的99mTc-MDP骨显像结果进行比较。所有病例均经活检和手术后组织学证实,其中恶性骨肿瘤33例,良性骨病变10例,软组织肉瘤10例,软组织良性肿瘤5例。结果半定量分析43例恶性病变和15例良性病变的早期UR分别为2.856±1.121和1.304±0.324,两者的差异有显著性意义(t=5.259,P<0.001);两者的延迟期UR分别为2.261±0.769和1.100±0.139,其差异有显著性意义(t=5.786,P<0.001)。假设早期UR>1.735(2.856-1.121)且延迟期UR>1.492(2.261-0.769)为鉴别良、恶性的阈值,则敏感性为95.35%、特异性为93.33%、精确性为94.83%。6例骨肉瘤病例术前新辅助化疗前后201Tl显像显示变化率与肿瘤坏死率存在良好的相关性,对化疗敏感(TNR>90%)的5例病例化疗后201Tl显像示病灶摄取明显减少。结论201Tl显像的定量研究对骨与软组织病变良、恶性鉴别有重要的临床价值;本研究结果推荐早期UR>1.735,且延迟期UR> 展开更多
