A 50-year-old woman presented with pain, swelling, and reduced range of motion of right knee joint since one year. Radiograph of knee joint revealed eccentric, expansile, geographic lytic lesion on the medial epiphyseal region of tibia mimicking giant cell tumor (GCT). She underwent minimally invasive biopsy, which was positive for acid-fast bacilli and revealed necrotizing chronic granulomatous lesion, diagnostic of tuberculosis (TB). This case emphasizes to consider tuberculosis arthritis as differential diagnosis when a case of destructive giant cell tumor is encountered.
一名50岁女性自一年前起出现右膝关节疼痛、肿胀及活动范围减小。膝关节X线片显示胫骨内侧骨骺区域有偏心性、膨胀性、地图样溶骨性病变，类似骨巨细胞瘤（GCT）。她接受了微创活检，结果显示抗酸杆菌阳性，并发现坏死性慢性肉芽肿性病变，确诊为结核病（TB）。该病例强调，当遇到破坏性骨巨细胞瘤病例时，应将结核性关节炎作为鉴别诊断之一。
