Split cord malformations rarely present with bony septum variations. This study details a unique case where a midline bony septum terminated as a complete spinous process, offering insights into developmental anomalies.

Area of Science:

  • Developmental biology
  • Neuroscience
  • Orthopedic surgery

Background:

  • Split cord malformations (SCMs) are congenital anomalies characterized by a longitudinal division of the spinal cord.
  • Bony septum variations within SCMs are infrequently documented, making their morphological spectrum poorly understood.
  • Understanding the embryological origins of these variations is crucial for accurate diagnosis and management.

Observation:

  • This report describes a rare case of split cord malformation featuring a midline bony septum.
  • The unique characteristic of this septum was its posterior termination as a fully formed, ossified spinous process.
  • This specific bony morphology has not been previously detailed in existing literature.

Findings:

  • The observed bony septum variation suggests a potential disruption in mesodermal cell migration during early fetal development (around the third week).

  • The primitive endomesenchymal tract's development may be implicated, leading to aberrant bony structure formation.
  • This finding highlights the diverse anatomical presentations of spinal cord anomalies.

    • Implications:

    • Clinicians managing patients with split cord malformations should be aware of this rare bony morphology.
    • Careful surgical planning is advised to avoid excessive manipulation of such spinous process-like structures.
    • Potential injury to the underlying hemicord during surgical intervention must be considered due to this anatomical variation.
