头颈部的神经鞘瘤相对较少见。我们报告一例起源于左侧脑神经的神经鞘瘤。一位21岁男性患者在本院就诊时左侧脸颊出现无痛性肿胀。由于病变的大小迅速增大，因此怀疑是恶性肿瘤。进行磁共振成像(MRI)、计算机断层扫描和超声检查。核磁共振和超声检查显示肿瘤与脑神经相连。MRI和超声检查对术前诊断均有帮助。手术前有可能确定这是一种周围神经鞘瘤。病变被完全切除。病理诊断为Antoni A型神经鞘瘤。术后1年未见复发迹象。
Schwannoma of the head and neck region is relatively uncommon. We report a case of schwannoma arising from the left mental nerve. A 21-year-old male presented at our hospital with a painless swelling of the left cheek. Because the lesion had rapidly increased in size, a malignant tumor was suspected. Magnetic resonance imaging (MRI), computed tomography, and ultrasonography were performed. MRI and ultrasonography revealed that the tumor was connected to the mental nerve. Both MRI and ultrasonography were found to be useful in making a preoperative diagnosis. It was possible to determine prior to surgery that this was a peripheral nerve sheath tumor. The lesion was completely resected. The pathological diagnosis was Antoni type A schwannoma. There has been no sign of recurrence 1 year after surgery.
