骨髓瘤病又称多发性骨髓瘤,常首先损害躯干骨骼,长期剧烈骨痛。作者观察以颞颌关节疼痛为首发症状的骨髓瘤病4例,均为女性,年龄分别为44,46,48和51岁。因双侧颞颌关节经常疼痛(3～4年)就诊,曾误诊为类风湿性关节炎,进行奴夫卡因局部封闭,离子导入和超高频电疗等无效。无关节运动障碍,开口不受限。颞颌关节X线摄影见关节间隙正常,下颌髁状突松质骨内有多个1～3mm大小的圆形或卵圆形透射区,界限清楚;骨皮质和关节盘无破坏,这可能是无关节运 Myeloma, also known as multiple myeloma, often first damages the torso bones and prolonged severe bone pain. The authors observed 4 cases of myeloma with temporomandibular joint pain as the first symptom, all of them were female, and the ages were 44, 46, 48 and 51 years old respectively. Due to frequent pain in the bilateral temporomandibular joints (3 to 4 years), he had been misdiagnosed as rheumatoid arthritis, and partial ozonocapto therapies, iontophoresis, and ultra high-frequency electrotherapy were ineffective. No joint movement disorders, opening is not limited. X-ray photographs of the temporomandibular joint showed normal joint space, and there were multiple circular or ovoid circular transmissive areas within the cancellous bone of the mandibular condyle; the boundaries were clear; the cortical and articular disks were not damaged, which may be No joint movement
