Congenital encephalocele is a rare condition where brain tissue protrudes through skull defects. This case highlights a congenital subcutaneous transmastoid encephalocele presenting as a postauricular mass, challenging initial diagnosis.

Area of Science:

  • Pediatric Neurosurgery
  • Otolaryngology
  • Congenital Malformations

Background:

  • Encephaloceles are uncommon pediatric abnormalities, typically found in the nasopharynx or nose.
  • Mastoid encephaloceles are rare, often linked to surgery, trauma, or infection.
  • Congenital encephalocele presenting in the mastoid with a subcutaneous postauricular mass is exceptionally rare.

Observation:

  • A case of congenital subcutaneous transmastoid encephalocele in a child is presented.
  • The right temporal lobe herniated through congenital defects in the tegmen and mastoid cortex.
  • The encephalocele presented as a postauricular subcutaneous mass, initially misdiagnosed as a subperiosteal abscess.

Findings:

  • Congenital encephalocele can manifest unusually, mimicking other conditions.

  • Preoperative CT scans may not reveal congenital transmastoid encephaloceles.
  • Surgical exploration is crucial for accurate diagnosis of such rare conditions.

    • Implications:

    • Highlights the importance of considering rare congenital anomalies in pediatric differential diagnoses.
    • Emphasizes the limitations of imaging in diagnosing complex congenital skull base defects.
    • Informs otolaryngologists and neurosurgeons on managing challenging encephalocele cases.
