title: Alkaptonuria presenting with ochronotic spondyloarthropathy.
abstract: Alkaptonuria is a rare autosomal recessive metabolic disease that leads to the deposition of homogentisic acid. Ochronotic arthropathy is the articular manifestation of alkaptonuria with the most common clinical feature being severe spondyloarthropathy. We present the case of a 58-year-old woman with back pain. Radiographs and magnetic resonance imaging (MRI) revealed characteristic features of ochronotic spondyloarthropathy. The literature regarding management of alkaptonuria is reviewed.
