摘要

由於病例少見而沒有想到，而且在疾病初期缺乏X光的發現，結核性膝關節炎不容易早期診斷。作者在此報告一位80歲的男性感染結核性膝關節炎而以膝膕囊腫表現的病例。早期診斷的關鍵是如果病人有不尋常的膝關節腫大及膝膕囊腫時，就應高度懷疑此一疾病。對於結核性膝關節炎的主要治療是合併使用多種抗結核藥物，以預防膝關節進一步的破壞。此疾病和敗血性膝關節炎的鑑別診斷是相當重要的。在懷疑的病例，早期的關節液培養及滑液膜切片檢查，可提供正確的細菌學和病理學的診斷。

The early diagnosis of tuberculous arthritis of the knee is difficult as knees are few early radiological signs and because it is rare or it is often not thought of this infection. The authors describe an 80-year-old patient with an unusual presentation of tuberculous arthritis involving the knee joint mimicking a popliteal cyst. The key to early diagnosis is a high index of suspicion when a patient has an unusual presentation of a popliteal mass with knee swelling. The main treatment for tuberculous arthritis of the knee usually consists of a combination of antituberculosis drugs to prevent further destruction of the joint. The diagnosis should be differentiated from pyogenic arthritis of the knee. Early synovial fluid culture and biopsy in suspected cases provide accurate bacteriological and pathological diagnosis.
