A Giant Basal Meningoencephalocele Repair in a Neonate: A Case Report

Area of Science:

• Neuroscience
• Developmental Biology
• Surgical Anatomy

Background:

• Primary encephaloceles are congenital mesodermal defects involving brain tissue protrusion through the skull.
• These defects occur most commonly in the occipital region but can manifest anywhere on the calvarium.
• Meningoencephaloceles, a subtype, involve herniation of both meninges and brain tissue.

Observation:

• Basal meningoencephaloceles associated with cleft palate defects represent an extremely rare presentation.
• This report details a case of a giant basal meningoencephalocele extending into the nasal and oral cavities.
• The anatomical complexity presented a significant risk of thecal sac rupture.

Findings:

• Giant basal meningoencephalocele involving the naso-oral cavities is exceptionally rare.
• Anesthetic management for such extensive defects requires careful consideration due to potential complications.
• The risk of thecal sac rupture is a critical factor in surgical planning.

Implications:

• This case underscores the importance of recognizing rare congenital skull base defects.
• Anesthetic strategies must be tailored to the unique anatomical challenges posed by giant basal meningoencephaloceles.
• Further research into anesthetic implications for these rare conditions is warranted to improve patient outcomes.
