[Anomalous course of a lipomeningocele].

A 9 months old male with a lipomeningocele developed progressive flaccid paraparesis with loss of deep tendon reflexes and sensation to pink prick on the lower extremities. The clinical picture was secondary to a tethered spinal cord syndrome associated to the lipomeningocele. Surgical untethering of the spinal cord was followed by clinical recovery over a 3 months period.
