Summary
Giant osteomas in the paranasal sinuses can cause rare intracranial issues like subdural empyema. This case highlights surgical management for a large frontoethmoidal osteoma with intracranial extension.
Area of Science:
- Neurosurgery
- Otolaryngology
- Radiology
Background:
- Osteomas of the paranasal sinuses are benign bone tumors.
- Intracranial complications from paranasal sinus osteomas are rare.
- Giant osteomas pose unique diagnostic and management challenges.
Observation:
- A 34-year-old male presented with seizures.
- Neuroradiological studies revealed a large right frontal sinus osteoma with frontoparietal subdural empyema.
- This represents the third reported case of subdural empyema complicating a frontoethmoidal osteoma.
Findings:
- Surgical resection of the osteoma and evacuation of the subdural empyema were performed in a single-stage decompressive craniotomy.
- The patient experienced an excellent recovery following surgery and antibiotic therapy.
- Analysis of literature suggests various surgical approaches for giant frontoethmoidal osteomas.
Implications:
- This case underscores the importance of considering intracranial complications in patients with large paranasal sinus osteomas.
- Optimal surgical strategies, including open and endoscopic techniques, should be tailored to the specific lesion.
- Further research into the pathogenesis of these rare intracranial extensions is warranted.
