Abstract

Objective:

There have been few previous reports of intraosseous schwannomas within the mandible with extension into the cranium. We report two such cases and discuss the relevant clinical features, radiological manifestations and treatment protocols.

Method:

Two case reports of trigeminal schwannoma of the mandible with intracranial extension, including analysis of clinical, radiological and pathological aspects.

Results:

Panoramic radiographs showed both tumours as multilocular radiolucencies. Solid and cystic components were seen on computed tomography and magnetic resonance imaging. The two tumours extended into the cranium through the pterygomandibular space and an obviously expanded foramen ovale.

Conclusion:

Trigeminal schwannoma of the mandible can develop to involve intracranial extension. Radiological identification of an expanded foramen ovale may facilitate pre-operative identification.
