title: Osteopenia in Crohn's disease.
abstract: A 16 year old boy presented soon after diagnosis of Crohn's disease with diffuse osteopenia of the lumbar spine with collapse of three vertebral bodies and grossly reduced bone mineral density noted on dual energy x ray absorptiometry scan. Treatment of the underlying Crohn's disease and induction of puberty resulted in marked improvement in bone mineralisation.
