Chronic sclerosing osteomyelitis of the iliac bone. Etiological possibilities

An adolescent with chronic recurrent multifocal osteomyelitis located to both iliac bones and an adult with pustulotic arthro-osteitis, involving the left iliac bone, an invertebral space, and the sternoclavicular, first sternocostal, manubriosternal and single peripheral joints are described. Their iliac bone changes were identical, except for the occurrence of bilateral changes in the adolescent, and ankylosis of the sacroiliac joint in the adult. It is suggested that chronic recurrent multifocal osteomyelitis and pustulotic arthro-osteitis may be related diseases with age-dependent differences. (orig.)
