Orbital meningocele in two case studies.

Area of Science:

• Ophthalmology
• Neurosurgery
• Medical Imaging

Background:

• Orbital meningocele is a rare congenital malformation involving meningeal herniation through orbital bone defects.
• It can also occur at natural openings or result from trauma.

Observation:

• Two patients presented with progressive proptosis due to orbital meningoceles.
• One case involved a congenital lesion, the other a traumatic orbital bony defect.
• CT scans aided diagnosis but one case was initially misdiagnosed as an arachnoid cyst.

Findings:

• Orbital meningoceles present with progressive proptosis.
• Congenital and traumatic etiologies are identified.
• Accurate diagnosis may require advanced imaging and clinical correlation.

Implications:

• Successful surgical correction is achievable for both congenital and traumatic orbital meningoceles.
• Early and accurate diagnosis is crucial for effective management.
• Understanding the diverse origins of orbital meningoceles improves patient outcomes.
