Herein, we present the case of a 68-year-old woman complaining of pain of the right knee, which was initially misdiagnosed by plain radiography as fracture on inner right tibia plateau but was finally clarified as osteolytic lesion secondary to syphilis affecting the whole right knee. The final diagnosis was made based on the valuable findings from bone scanning, which allows for imaging of abnormalities with much larger extent, a scale that is out of the examination capacity of plain radiography. Bone scanning was employed in this case, coupled with the use of 99mTc-MDP, to assess abnormal bone metabolism at the whole right knee next to the tibia plateau. The imaging results illustrated the diverse features of bone involvement of secondary syphilis, including periostitis, osteolysis as well as osteomyelitis, occurring together or in isolation.
目的:在对膀胱癌进行诊断时选用18F-FDG PETCT显像诊断,对其价值进行研究.方法:本研究纳入的对象为2015年1月—2017年1月我院收治的患有膀胱癌的40例患者,针对其进行病理学检查,再分别对其展开增强CT和18F-FDG PETCT显像诊断,增强CT诊断为A组,18F-FDG PETCT显像诊断为B组,对比两组诊断结果和肿瘤淋巴转移情况.结果:B组的诊断正确率及肿瘤淋巴转移准确率均高于A组,P<0.05具有统计学意义.结论:增强C T及18F-FDG PETCT显像诊断在膀胱癌患者的诊断中均具有良好的效果,但18F-FDG PETCT显像诊断对于肿瘤病灶转移情况的诊断价值更高.
1 患者资料 患者男性, 48岁,两年前面部出现皮疹伴瘙痒,无发热,于当地皮肤科多次治疗后均未见明显好转.2016年3月因意外摔伤导致面部皮损、红肿,遂于南京皮肤研究所诊治,诊断为银屑病,予软膏外敷治疗后仍未见好转.该患者在治疗前签署了知情同意书,并且该研究获得了江苏省苏北人民医院伦理委员会的批准.2016年11月于本院皮肤科就诊,取皮肤活检,组织病理学结果表现为真皮全层及皮下脂肪内结节性或弥漫性中等及较大多形性淋巴样细胞浸润;结合苏木精-伊红染色法形态及免疫组化结果,首先考虑T细胞淋巴瘤,部分有亲毛囊现象,部分区域伴反应性B细胞增生.该患者后经复旦大学附属肿瘤医院确诊为(面部皮损,活检)外周T细胞淋巴瘤-非特指型(peripheral T-cell lymphomas-unspecified, PTCL-U)(图1).EB病毒编码的小RNA原位杂交检测结果为阴性,提示无人类疱疹病毒4型感染.随后进行PET/CT检查.采用GE Discovery VCT型PET/CT仪,其中CT为64排螺旋CT,显像剂为 18F-FDG (上海原子科兴药业有限公司),放化纯度>95%.
