Abstract

A number of research papers have reported more frequent occurrence of rheumatic/autoimmune disease among patients with hypogonadism or a chromosomal anomaly with potential X-chromosome defects. A 30-year-old female patient came to the hospital with a main cause of bilateral buttock pain, which began two years ago and worsened seven days ago. Ankylosing spondylitis with invasion of both sacral-iliac joints was observed. On magnetic resonance imaging, although the uterus was observed normally, an ovary was not observed. In a chromosome test, balanced reciprocal X-1 translocation of 46,X,t(X;1)(p10;q10) was diagnosed. Here, we report on the first case involving ankylosing spondylitis accompanied by balanced reciprocal X-1 translocation.
