Case report of a mental nerve neurilemmoma

We present a case of a mental neurilemmoma with characteristic findings on cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI). A 62-year-old man was referred to our hospital for a painless swelling in the right cheek. CBCT imaging demonstrated dilatation of the mental foramen. On MRI, a layered pattern on T2-weighted images and enhancement with gadolinium were observed within a low-signal pseudo-capsule. On the basis of these findings, a neurilemmoma was considered likely, and this diagnosis was confirmed histologically.
