[Thoracic meningocele]

Area of Science:

• Neurology
• Developmental Biology
• Surgical Anatomy

Background:

• Spinal meningoceles, characterized by meningeal herniation through spinal canal defects, are predominantly found dorsally in the lumbosacral region.
• These congenital anomalies are often associated with complex developmental disorders, systemic diseases, or can be iatrogenic.
• The typical presentation involves dorsal location, making anterior occurrences exceedingly uncommon.

Observation:

• This case report focuses on a highly unusual presentation of a true anterior thoracic meningocele.
• The anatomical location in the thoracic region, anteriorly, deviates significantly from the usual dorsal lumbosacral findings.
• Detailed clinical and radiological findings of this rare anatomical variant are presented.

Findings:

• The study documents a rare case of anterior thoracic meningocele, challenging the typical understanding of meningocele location and etiology.
• This finding underscores the variability in congenital spinal defects and their potential for atypical presentations.
• The case highlights the importance of considering rare anatomical variations in the differential diagnosis of spinal pathologies.

Implications:

• This case expands the known spectrum of spinal meningocele presentations, particularly concerning location.
• Understanding such rare anatomical variations is crucial for accurate diagnosis and surgical planning in neurosurgery.
• Further research into the embryological basis of anterior thoracic meningoceles may provide insights into spinal development.
