少见部位肺结核的影像表现及其误诊原因分析

目的分析少见部位肺结核的影像学表现及误诊原因。方法回顾性分析临床确诊的83例少见部位肺结核的影像学表现。结果初诊正确48例,误诊29例,漏诊6例。影像学表现为斑点状、斑片状、大片状、空洞、肿块、条索状、钙化影或纵隔肿块。结论大部分少见部位的肺结核具有典型的影像学表现,但确诊需依靠X线、CT检查结合临床表现及实验室检查。

Imaging findings of uncommon location pulmonary tuberculosis and its analysis of misdiagnostic causes

Objective To analyze the imaging findings of uncommon location pulmonary tuberculosis and its misdiagnostic causes.Methods Imaging findings of 83 patients with clinically known uncommon location pulmonary tuberculosis on conventional X-ray chest films and CT images were analyzed retrospectively.Results Initially based on imaging findings of 83 cases,correctly diagnosed 48 cases,misdiagnosed 29 cases,and leak-diagnosed 6 cases.The lesions of pulmonary tuberculosis appeared as mottling,matchy,large-matchy,cavitary,mass-form,and striped calcification shadows or associated with mediastinal masses.Conclusion The majority of uncommon location pulmonary tuberculosis have typical imaging findings but the definite diagnosis of this disease depends on the combination of conventional X-ray chest film with computed tomography（CT）,clinical manifestation,and laboratory test.
