Summary
Primary intraosseous cavernous hemangiomas (PICHs) are rare skull base tumors. This case highlights their diagnostic challenges and successful surgical removal via an extradural frontopolar approach.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Primary intraosseous cavernous hemangiomas (PICHs) are exceptionally rare tumors.
- These vascular lesions most frequently occur in the frontal and parietal bones of the calvarium.
Observation:
- A 40-year-old female presented with progressive headaches.
- Imaging revealed a contrast-enhancing lesion in the sphenoid bone, encroaching on the cavernous sinus and displacing the carotid artery.
- The lesion demonstrated slow growth over 9 years.
Findings:
- Complete surgical excision of the PICH was achieved through an extradural frontopolar approach.
- Pathological examination confirmed the diagnosis of an intraosseous cavernous hemangioma.
- PICHs of the skull base can mimic other lesions, complicating preoperative diagnosis.
Implications:
- Skull base PICHs present diagnostic challenges due to their rarity and potential to mimic other pathologies.
- Early and accurate diagnosis is crucial for effective management.
- Surgical intervention, such as the extradural frontopolar approach, can be curative.
