肺炎性假瘤的X线诊断

X-RAY DIAGNOSIS OF INFLAMMATORY PSEUDOTUMORS OF LUNG

1目的 提高 X线对肺炎性假瘤的诊断水平。2方法 对临床与 X线检查资料较全并经手术病理证实的 31例肺炎性假瘤进行回顾性分析。 3结果 31例肺炎性假瘤中 X线诊断正确者仅 5例 ,占 16 % ;误诊为肺癌12例 ,占 39% ;良性病变 10例 ,占 32 % ;结核瘤 3例 ,占 10 % ;错构瘤 1例 ,占 3% .总误诊 2 6例 ,占 84% .4结论肺炎性假瘤 X线表现以肺部“桃尖征”为较特征性改变。对诊断确有困难者 ,经皮穿刺行病理细胞学检查有助于明确诊断。

Objective To improve the standard of X ray diagnosis of inflammatory pseudotumors of the lung.\ Methods 31 cases of inflammatory pseudotumors of the lung with clinical and X ray data confirmed by operation and pathology were analyzed retrospectively.\ Results\ Only 5 cases were accurate diagnosis by X ray(16%), misdiagnosed as lung cancer was 12 cases(39%), benign lesions 10(32%),tuberculoma 3(10%),hamartoma 1(3%).The misdiagnosis was 26 cases, accounting for 84%. Conclusion \ Peach peak sign' is characteristic in X ray diagnosis of inflammatory pseudotumors of lung. [
