Spinal Dysraphisms: A New Anatomical-Clinicoradiological Classification

Area of Science:

• Pediatric Radiology
• Developmental Biology
• Neuroscience

Background:

• Spinal dysraphisms are congenital spine and spinal cord abnormalities.
• Embryological origins of complex spinal dysraphisms are not fully understood.
• Existing classifications lack inclusion of complex and recently documented dysraphisms.

Purpose of the Study:

• To review imaging features of spinal dysraphisms.
• To enhance understanding of embryological abnormalities.
• To propose a new classification based on anatomical and clinicoradiological correlation.

Main Methods:

• Retrospective observational study of 391 spinal dysraphism cases over 10 years.
• Analysis included patient demographics (age, sex) and imaging findings.
• Data analyzed for anatomical-clinicoradiological correlation.

Main Results:

• Spinal lipomas (lipomyeloceles, lipomyelomeningoceles) were most common (31.3%).
• Posterior myelomeningocele accounted for 14.2% of cases.
• Anterior myelocoele, sacral chordoma, and intrasacral meningocele were least common (0.2% each).

Conclusions:

• A structured imaging approach is crucial for evaluating spinal dysraphisms.
• The proposed classification incorporates unusual and complex dysraphisms.
• The new classification is based on clinicoradiological correlation and anatomical location.
