Sphenoid Wing Meningioma With Extraocular Muscle Involvement Mimicking Idiopathic Orbital Inflammation

Area of Science:

• Neurosurgery
• Ophthalmology
• Oncology

Background:

• Meningiomas are typically benign tumors arising from arachnoid cap cells.
• Spheno-orbital meningiomas specifically affect the sphenoid bone and orbit.
• These tumors can compress cranial nerves and affect vision.

Observation:

• Extraocular muscle enlargement is a rare presentation of spheno-orbital meningioma.
• This enlargement can mimic idiopathic orbital inflammation, complicating diagnosis.
• The case highlights the importance of considering meningioma in orbital pathologies.

Findings:

• The presented case demonstrates an spheno-orbital meningioma causing significant extraocular muscle hypertrophy.
• Diagnostic imaging and clinical evaluation are crucial for differentiating meningioma from inflammatory conditions.
• Early detection prevents irreversible neurological and ophthalmological damage.

Implications:

• Recognizing subtle signs of meningioma is vital for timely intervention.
• This case underscores the need for a broad differential diagnosis in orbital diseases.
• Improved diagnostic strategies can lead to better patient outcomes for spheno-orbital meningiomas.
