肺外結核感染在臨床上有多種不同的表現，感染部位可遍及全身。由於難以獲得微生物進行診斷，通常使用實驗室檢查、影像學檢查及病理檢驗作為間接證據進行推論診斷；此外，經驗性抗結核桿菌藥物治療的成效也是診斷的線索之一。本篇文章介紹一位肺外結核感染併縱膈腔淋巴腺病變及眼結核之患者，其診斷有賴臨床判斷及病理檢查，介入標準結核病治療，病患得到良好的預後。

Extrapulmonary tuberculosis has variable clinical manifestations, and the infection sites can be anywhere in the body. Owing to the difficulty in obtaining a microbiological diagnosis, it is common to make a presumptive diagnosis using laboratory data, imaging studies, and pathological examination as indirect evidence. In addition, the treatment response to the empirical antituberculosis regimen indicates whether tuberculosis is the correct answer. Here, we present a case of extrapulmonary tuberculosis with multiple mediastinal lymphadenopathies and ocular involvement. The diagnosis was made based on the relevant clinical presentations and typical pathological reports. The patient recovered well after empirical antitubercular treatment. A comprehensive study should be attempted and would provide further help to build the diagnosis.
