Summary
This case report details an ossifying fibroma, a rare benign fibroosseous tumor, found in the cranial vault. The study highlights the rarity of this specific location for ossifying fibromas.
Area of Science:
- Neurosurgery
- Pathology
- Radiology
Background:
- Ossifying fibroma is a rare benign fibroosseous tumor.
- While typically found in the jaw and paranasal sinuses, it can occur in the cranial vault, though infrequently.
Observation:
- A 76-year-old woman presented with headache after head trauma.
- Skull X-ray revealed a 4x4 cm radiolucent lesion in the temporal bone.
- Bone scintigraphy showed characteristic doughnut-shaped uptake.
Findings:
- Microscopic examination confirmed immature bone spicules and fibrous tissue, consistent with ossifying fibroma.
- Serum calcium, phosphorus, and alkaline phosphatase levels were normal.
- The tumor was surgically removed, followed by cranioplasty.
Implications:
- This case adds to the limited number of reported ossifying fibromas in the cranial vault.
- Highlights the importance of considering rare lesions in cranial vault pathology.
- Further research into the etiology of cranial vault ossifying fibromas is warranted.
