title: Ossified dysraphic hamartoma with lipomyelocoele/lipomyelomeningocoele-A rare radiological entity.
abstract: Traditionally the presence of fat in closed spinal dysraphism has been referred to as spinal lipoma. Recent reports suggest that these spinal lesions are better described as spinal hamartomas due to the unencapsulated and infiltrating nature of the fat and presence of other heterotopic soft tissue. The presence of ossified bone in spinal hamartomas referred to as ossified dysraphic hamartoma, is extremely rare with only three case reports in literature, all associated with lipomyeloceles, none with lipomyelomeningoceles. We present three cases of ossified dysraphic hamartoma, two of them associated with lipomyelomeningoceles, reviewing imaging features on CT and MRI.
