Temporomandibular joint (TMJ) arthritis is frequently seen in children with chronic arthritis. It has rarely been described in a non-infectious acute setting. We report a case of reactive arthritis isolated to the TMJs and cervical spine.
A 6-year-old Native American boy hospitalized for treatment of lymphadenitis and aseptic meningitis had an incidental brain magnetic resonance imaging (MRI) finding of effusions in the TMJs, as well as the atlanto-occipital and C1-C2 articulations. Repeat TMJ and cervical spine MRI four weeks later showed resolution of effusions. Reactive TMJ arthritis has been previously reported in adults but not in children.
This report represents the first pediatric case of reactive arthritis isolated to the cervical spine and TMJs. Arthritis of the TMJ should be considered in the differential diagnosis of children with reactive arthritides.
颞下颌关节（TMJ）关节炎在患有慢性关节炎的儿童中很常见。在非感染性急性情况下很少有相关描述。我们报告一例仅累及颞下颌关节和颈椎的反应性关节炎病例。
一名因淋巴结炎和无菌性脑膜炎住院治疗的6岁美国原住民男孩，在脑部磁共振成像（MRI）检查时意外发现颞下颌关节以及寰枕关节和C1 - C2关节有积液。四周后重复进行的颞下颌关节和颈椎MRI检查显示积液已消退。反应性颞下颌关节炎此前在成人中有报道，但在儿童中未见报道。
本报告代表了首例仅累及颈椎和颞下颌关节的儿童反应性关节炎病例。在对患有反应性关节炎的儿童进行鉴别诊断时应考虑颞下颌关节关节炎。
