Vertebral choristoma in lipomyelomeningocele: a case report

Lipomeningocele is a type of occult spinal dysraphism characterized by a subcutaneous lipomatous mass that protrudes through a midline bony defect. We report a rare presentation of this condition--a vertebral choristoma wherein the lipomatous mass displaced the normally formed posterior elements--lamina and spinous process of L4 vertebra dorsally to an abnormal location in the absence of a bony defect.
