目的总结肺结节病影像学特征,提高影像学对结节病的诊断水平。方法复习2002年11月至2005年12月搜集的9例肺结节病患者的病理和影像学资料。结果 9例中胸片示2例一侧肺门淋巴结肿大,6例肺纹理增多。5例CT表现为纵隔肺门淋巴结对称性肿大,肺内弥漫性结节影2例,粟粒结节灶1例。5例核医学显示肺门淋巴结肿大伴放射性代谢增高,9例显示为＂熊猫脸＂征伴＂λ＂征。3例PET-CT影像特征为淋巴结PDG代谢异常增高。9例均经支气管镜或胸腔镜和纵隔镜取病理证实。结论影像核医学和PET-CT检查手段是诊断肺结节病的可靠方法,结合病理检查诊断率高,值得临床推广应用。 相似文献

目的 :了解肺结节病的临床表现的不典行性和确诊方法 ,从而加深对肺结节病的认识。方法 :回顾分析了 64例经病理证实的肺结节病患者的全部资料。结果 :根据X线征象诊断或考虑为肺结节病的确诊率为 59.3% ,经支气管镜粘膜活检的确诊率为 67.5 % ,经支气管镜肺活检(TBLB )的确诊为率 62 .5 % ,PPD试验阴性者 82 .8% ,常规行SACE检查增高者为73 .4%。结论 :因肺结节病临床表现具多样性和不典型性 ,故易导致漏诊和误诊。其诊断依赖病史、临床表现、X线、支气管镜、肺活检等多种方法 ,病理诊断是主要的确诊依据。并提倡对可疑的肺结节病患者应尽早行支气管镜粘膜活检或经TBLB检查 ,以期早日明确诊断 相似文献

五年一贯制高职是我国高等职业教育的一种重要形式,《幼儿教师口语》是五年一贯制学前教育专业的一门专业基础课,授课内容应与＂3＋2＂学制有所区别。根据五年一贯制学前教育专业人才培养方案的要求,《幼儿教师口语》应在课程教学计划、教材衔接、课程教学内容、师资队伍和教学方法等方面做好与《汉语基础》课程的衔接工作,关注学生前三年的口语基础,重在提升学生教育教学口语的设计与应用。 相似文献

Background： The purpose of this study was to describe our experiences and analyze the benefits of video-assisted thoracoscopic surgery （VATS） combined with positron emitted tomography （PET）-computed tomography （CT） in the diagnosis of patients with early （Stage 1） sarcoidosis. Methods： From 1995 to 2006, seven patients （two males, five females）, with ages ranging from 26 to 58 years, were impressed with Stage 1 sarcoidosis （mediastinal or hilar lymph nodes involvements without lung involvement） by histological examination of intrathoracic lymph nodes （LNs） and/or lung parenchyma taken＇from VATS biopsy. Three of them received PET or PET-CT evaluation. VATS was approached from the right and left side in one and six patients, respectively, according to the locations of their lesions. Results： All the VATS biopsied LNs or lung specimens were adequate for establishing diagnosis. Mediastinal LNs were taken from Groups 3, 4 in four, Group 7 in two, and Groups 5, 6 in one of them. Hilar LNs biopsies were performed in four cases. Lung biopsy was performed in all but two cases. All of them were expressed pathologically or radiologically as Stage 1 sarcoidosis. PET-CT revealed high emission signals over these affected LNs. These patients received oral steroid treatment or follow up only. All of them were followed up from 5 months to 11 years with satisfactory results. Conclusion： VATS biopsy is a minimally invasive, safe and effective procedure. It can be used as a diagnostic altermative of transbronchial lung biopsy （TBLB）, and can harvest larger and more areas of specimens than mediastinoscopy for staging patients with sarcoidosis. PET-CT can provide us more accurate information about the characteristics and localization of these lesions before biopsy. VATS combined with PET-CT can provide more accurate and earlier diagnosis of patients with unknown intrathoracic lesions, including the sarcoidosis. 相似文献
