Abstract:
Rice body formation is a rare response to chronic inflammation of the synovial membrane. It is most commonly associated with rheumatoid arthritis and tuberculosis. Recently, there have been reports of rice bodies caused by non-tuberculous mycobacterial infection. We describe a case of rice body formation in a 69-year-old man who presented with pain and swelling in his third finger for six months after being punctured by a wire 1 year ago. He had no other notable recent medical history. Magnetic resonance imaging showed a large amount of fluid collection with diffuse thickening and enhancement of the synovium and rice bodies along the flexor tendon of the third finger. During surgery, multiple granular white rice bodies were found from the third carpal bone to the distal phalanx. Mycobacterium intracellulare was identified through mycobacterial culture and the patient was treated with rifampin, ethambutol, and clarithromycin, without recurrence. This case reveals that Mycobacterium intracellulare infection can cause tenosynovitis with rice bodies.
摘要:
水稻体形成是一种罕见的滑膜慢性炎症反应。它最常见的是与类风湿性关节炎和肺结核有关。最近,有报道称非结核分枝杆菌感染引起水稻体。我们描述了一名69岁男子的水稻体形成病例,该男子在1年前被电线刺穿后,第三根手指出现疼痛和肿胀六个月。他没有其他值得注意的近期病史。磁共振成像显示大量液体聚集,沿着第三指的屈肌腱弥漫性增厚和滑膜和水稻体增强。手术期间,从第三腕骨到远端指骨发现了多个颗粒状白色水稻体。通过分枝杆菌培养鉴定细胞内分枝杆菌,患者接受利福平治疗,乙胺丁醇,还有克拉霉素,没有复发。该病例表明,细胞内分枝杆菌感染可引起水稻体腱鞘炎。
