Axial Osteosclerosis

A very rare benign bone disorder with characteristics of bone dysplasia manifested by patchy sclerosis of the axial skeleton and increased bone mineral content. The disease may be underdiagnosed due to confusion with autosomal dominant osteopetrosis. The condition is usually found incidentally on radiological examination and is very mild, sometimes accompanied by pain. Increased density of the vertebral plates, pelvis and occasionally of the upper femur have been reported, as well as kyphoscoliosis and femoral cysts.
