Summary
This case report details an extremely rare intracranial osteoma originating from the dura. Surgical resection confirmed the benign bone tumor, highlighting a unique dural lesion.
Area of Science:
- Neurosurgery
- Oncology
- Radiology
Background:
- Osteomas are typically benign bone tumors found in long bones.
- Intracranial osteomas are exceptionally rare, with dural origin being even rarer.
- This report focuses on a unique case of an intracranial osteoma attached to the dura.
Observation:
- A 35-year-old male presented with recurrent vertigo.
- Imaging revealed a dense, calcified mass in the right frontal area.
- MRI confirmed dural origin with specific T1 and T2 signal characteristics.
Findings:
- The lesion was a 5 cm diameter, 2 cm thick mass.
- Preoperative diagnosis was calcified meningioma.
- Histopathology confirmed the mass as an osteoma.
Implications:
- This case expands the understanding of rare intracranial tumors.
- Highlights the importance of comprehensive diagnostic imaging (CT, MRI) for accurate diagnosis.
- Contributes to the literature on dural-based osteomas and their surgical management.
