【摘要】 目的 :探讨胸部CT扫描对肺结核瘤的诊断价值。方法 :分析经临床病理证实的 15例肺结核瘤的胸部CT影像学资料。结果 :病灶直径 <4cm的肺结核瘤多呈类圆形、边缘光滑、密度均匀 ,常见钙化、周围卫星灶邻近胸膜增厚。少见浅分叶、稀疏长毛刺、近心端小空洞和中间略低密度等。直径 >4cm的病灶多呈浅分叶或形态不规则、密度不均匀、边缘光滑、多见钙化、周围卫星灶、稀疏毛刺近心端空洞和中间略低密度等。感兴趣区增强扫描均呈包膜强化或不强化 ,少见均匀强化。结论 :胸部CT扫描对本病有重要诊断价值。常见的胸部CT表现 ,特殊的发病部位 ,结合临床资料和普通X线检查 ,一般能做出正确诊断 ,CT表现不典型的最终有赖于病理检查更多还原

【Abstract】 Objective To evaluate the diagnostic value of chest CT scanning in pulmonary tuberculomas.Methods The clinical and CT imaging materials of 15 patients with pulmonary tudervulomas wereanalyed.Results When pulmonary tuberculomas diameter smaller than 4 cm,it’s usual finding included:round like nodule,smooth margin,homogeneous density,calcification,satellite lesions,thickened pleura.Unusual findings included:lobulated margin,an coarse spiculnion,near small cavitation,low densities in nodule,etc.When the nodule diameter greater than 4cm,it’s usual findings included:lobulated margin,unhomogeneous densities,smooth margin ,an coarse spiculation,calcification,satellite lesions,near small cavitation.Low densities in nodule etc.Contrast enhanced CT show round enhancement or noenhancement,uncommon homogeneous enhancement.Conclusion Chest CT scanning are of vallue for the diagnosis of the diseace,it’s possible to diagnosis of pulmonarytuberculomas by usual imaging manifestltions,special partes,clinical symptoms andplain chest flim,atypical CT findings,a definitiv diagnosis,depend on patholoical evidece.更多还原
