Widely separated composite split cord malformation

Area of Science:

• Pediatric Neurology
• Developmental Biology
• Spinal Cord Anomalies

Background:

• Split cord malformation (SCM) is a rare congenital anomaly involving the division of the spinal cord.
• SCMs typically occur as a single event, with varying locations along the spinal axis.
• Understanding the embryological basis of SCM is crucial for diagnosing and managing these complex conditions.

Observation:

• An 18-month-old child presented with split cord malformations (SCMs).
• The SCMs were identified at two distinct and widely separated levels: the upper thoracic (T2) and lumbar (L2) regions.
• This dual-level occurrence represents a rare anatomical variation.

Findings:

• The case highlights the possibility of split cord malformations occurring at multiple, distant spinal cord levels.
• Radiological and clinical findings confirmed the presence of SCMs at both T2 and L2.
• The rarity of this specific presentation (wide separation) is emphasized, with few similar cases reported.

Implications:

• This case expands the known spectrum of split cord malformation presentations.
• It underscores the importance of thorough spinal imaging in pediatric patients with suspected congenital anomalies.
• Further research into the developmental mechanisms underlying multiple SCMs may be warranted.
