高海拔地区肺结核影像表现65例回顾分析

目的：探讨总结高海拔地区肺结核的影像特点，更好的指导临床早期诊断。方法：回顾分析65例西藏高原肺结核的影像特点，总结分析其征象及价值。结果：原发型肺结核3例（5％），影像表现边缘清楚、密度均匀的致密影，伴有淋巴结增大；侵润型结核31例（48％），影像表现成分混杂的致密影，可见钙化及卫星灶；血行播散型结核27例（42％），影像表现两肺弥漫分布的结节影；纤维空洞肺结核4例（5％），影像表现空洞、纤维化、支气管播散三大特征。结论：高原地区肺结核以侵润型和血行播散型为主，有特定的影像特点，可以用来进行诊断。

The Retrospective Analysis of 65 Cases of Pulmonary Tuberculosis in Tibet Highland

Objective： To investigate the characteristics of medical imaging for the early diagnosis of pulmonary tuberculosis in highland. Methods： We retrospectively analyzed the features of medical imaging of 65 cases with pulmonary tuberculosis in Tibetan Plateau. Results： 3 cases （5%） were primary pulmonary tuberculo- sis. Pathological changes with clear margin and even density were found. Intumescent lymph nodes was concurrence. 31 cases （48%） were infiltrative pulmonary tuberculosis. The density ofthe pathological changes is miscellaneous. Calcification and satellite could be found. 27cases （42%） were hematogenous disseminated pulmonary tuberculosis. Pervasive nodule in the two lung could be found. 4cases （5%） were fiber and cavitary pulmonary tuberculosis. Fiber, eavity and dissemination by bronchus were the characteristics in medical imaging. Conclusion： Invasion type and hematosenous disseminated type are the dominating type of pulmonary tuberculosis in Tibetan Plateau, with specific imaging features,which can be used for diagnosis of pulmonary tuberculosis.
