A 71 year old woman suffering from ankylosing spondylitis with aggressive peripheral joint disease for 46 years developed unusual radiographic features in the hips and knees. The pathogenic processes responsible are uncertain, and no histology is yet available. Although she had been treated with radiotherapy to the knees, there was no similar history to explain the hitherto unreported appearance of the hips.
一名71岁女性患强直性脊柱炎伴侵袭性外周关节疾病46年，髋部和膝部出现了异常的影像学特征。致病过程尚不确定，且尚无组织学检查结果。尽管她曾接受过膝关节放疗，但没有类似病史可以解释髋部迄今未报道过的表现。
