A 17-year-old @entity1 had suffered from right ankle @entity4841 when he was 13 years old. He also had bilaterally congested conjunctivas and were erythematous around his right ankle joint. A soft tissue echo showed swelling of the right ankle joint. A Ga 67 scan revealed a focal elevated uptake in the right ankle, but a bone scan was negative. @entity625 was suspected due to @entity2024 , @entity625 and a previous episode of watery @entity294 . An ophthalmologic examination showed no evidence of @entity1596 . Laboratory data were negative for rheumatoid factor, antinuclear antibody and anti-ds DNA. Erythrocyte sedimentation rate (ESR) was 40 mm/hr and a histocompatibility test was positive for antigen B27. Based on the diagnosis of @entity2688 and reactive @entity625 , @entity6101 and @entity1623 were given for 14 days. During follow-up at the OPD, bilateral @entity4841 of the ankle joints was noted and a sonography showed bilateral @entity4 . @entity1691 ( @entity1691 ) was suspected. Two years later, he had @entity615 and @entity4841 of the knee joints with @entity1596 of the right eye. He was treated with @entity1623 and @entity617 . Because few @entity1691 cases initially present as axial @entity2720 or @entity627 and @entity1596 is uncommon in @entity1 , we presented the case with a review of literature and conclusion that the possibility of @entity1691 should be considered in young adolescent @entity1 with @entity625 of the lower limbs, @entity4932 , a family history of related diseases and positive @entity1530 , as well as negative rheumatoid factor (RF) and anti-nuclear antibody (ANA) results.
