[Takayasu arteritis with pulmonary artery involvement initially presenting as community-acquired pneumonia].

The initial clinical manifestations of pulmonary artery involvement in Takayasu arteritis were complicated and non-specific, making early diagnosis difficult. Three cases of Takayasu arteritis with pulmonary artery involvement (TA-PAI) initially presenting as community-acquired pneumonia (CAP) were reported. The clinical characteristics and lab test results of the three cases were summarized, and the relevant literature on TA-PAI mimicking CAP was concomitantly reviewed. It might be helpful in the early recognition and diagnosis of such patients.以肺动脉受累及为首发的Takaysu大动脉炎临床表现复杂，并缺乏特异性，早期诊断困难。本文报道3例初始表现为社区获得性肺炎（CAP），最终确诊为大动脉炎肺动脉受累（TA-PAI）的病例及其特点，并结合相关文献复习，总结这类病例早期临床及辅助检查特征，以期提高临床对TA-PAI的早期识别和诊断。.
