| Abstract;Neurilemoma (Schwannoma) is a benign tumor originating from Schwann sheath. Although it often occurs in the head and neck regions, occurrences in an oral cavity are relatively rare. We have experienced a case of neurilemoma in the glossal muscle. A 13-year-old female patient complained of an intra-glossal tumor. A smooth, 2-cm, elastic hard mass without tenderness was palpable in the left side of her tongue. Ultrasound examination revealed a well-margined, low echoic area. The margin of the mass was rich in blood flow. On magnetic resonance imaging (MRI), the mass showed decreased signal on T1-weighted images and increased signal on T2-weighted images. Moreover, the mass was enhanced by gadolinium on T1-weighted images. The encapsulated mass was surgically removed, and the pathological diagnosis was neurilemoma (Antoni type AB). MRI examination may be useful in diagnosing this tumor. (author abst.) |
