Osteitis condensans ilii is an entity which should be considered in the differential diagnosis of pain in the low part of the back. Diagnosis can be confirmed by roentgenologic examination. To our knowledge, this is the first case reported in an American Indian. The cause and pathogenesis of this entity is unclear and it is suggested that anti-inflammatory agents may be of benefit in certain cases.
