Summary
Intraosseous meningiomas (IOMs) in the temporal bone can mimic chronic otitis media. Early consideration of IOMs is crucial for patients with significant hyperostotic changes in the temporal bone.
Area of Science:
- Neurosurgery
- Otolaryngology
- Pathology
Background:
- Intraosseous meningiomas (IOMs) are rare intracranial tumors, representing about 1% of all meningiomas.
- These tumors are characterized by their en plaque growth pattern.
- Temporal bone IOMs present unique diagnostic challenges, often mimicking other otologic conditions.
