Diastematomyelia with hemimyelomeningocele: An exceptional and complex spinal dysraphism

Variations in split cord malformation (SCM) have been described earlier. However, a true hemimyelomeningocele (HMM) as only congenital malformation is extremely rare and is reported infrequently in published literature. We are reporting the case of a 3-month-old girl child who presented with a swelling on the lower back since birth. Magnetic resonance imaging revealed a type 1 SCM with right hemicord forming a HMM. Precise diagnosis and thorough anatomical detail of dysraphism is essential for optimal, individualized neurosurgical management.
