Alkaptonuria and ochronotic spondyloarthropathy: a delayed imaging diagnosis

A 49-year-old man with a history of non-Hodgkin lymphoma was referred to our clinic for surveillance body computed tomography. His medical history was remarkable for a persistent, progressive low back pain and generalized joint pain since early adulthood. On examination, he had a kyphoscoliotic spine with restriction of motion in all directions, and pigmentation on sclerae and ears. On computed tomography scans, no lymphoma lesion was detected, but there were prostatic calculi, atypical symphysis pubis arthrosis, and severe spondyloarthropathy with disc calcifications suggesting alkaptonuric ochronosis (Figs. 1 and 2).
