Summary
This report details a rare oral floor schwannoma case. Characteristic CT and MRI findings suggest schwannoma should be considered in oral floor mass diagnoses.
Area of Science:
- Oral pathology
- Neurosurgical oncology
- Radiology
Background:
- Schwannomas are rare tumors arising from Schwann cells.
- Oral floor schwannomas are exceptionally uncommon, posing diagnostic challenges.
Observation:
- A 49-year-old woman presented with a painless oral floor swelling.
- Imaging revealed a well-defined, oval sublingual mass with significant cystic degeneration.
Findings:
- Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a thickened, enhancing wall and fluid level within the mass.
- Histopathological examination confirmed the diagnosis of schwannoma.
Implications:
- Characteristic CT and MRI findings can aid in diagnosing rare oral floor schwannomas.
- Radiologists and clinicians should include schwannoma in the differential diagnosis for oral floor masses exhibiting these imaging features.
