The authors present a rare case of benign schwannoma arising in the pterygopalatine fossa. The patient, an 18-year-old female, initially noticed blurring of her left eye but later, sudden loss of her left vision occurred. Radiological and computed tomographic studies outlined a mass occupying the left pterygopalatine fossa, which extended into the middle cranial fossa, the maxillary, ethmoid and sphenoid sinuses and the orbit. The histology of a transantral biopsy was reported as a benign schwannoma. The tumor was successfully removed by a transmaxillary approach. The eye symptoms disappeared four weeks following surgery. The nerve of origin of the tumor was not identified. The authors posturate that erosion of the skull base with mild to moderate extension into the middle cranial fossa, does not appear to be a contraindication for excising a schwannoma by the transmaxillary approach in this area.
作者报告了一例罕见的起源于翼腭窝的良性神经鞘瘤病例。患者为一名18岁女性，最初发现左眼视物模糊，随后左眼突然失明。影像学和计算机断层扫描研究显示，有一个肿块占据了左侧翼腭窝，并延伸至中颅窝、上颌窦、筛窦、蝶窦和眼眶。经鼻窦活检的组织学报告为良性神经鞘瘤。通过经上颌入路成功切除了肿瘤。术后四周眼部症状消失。未确定肿瘤的起源神经。作者推测，颅底有侵蚀且轻度至中度延伸至中颅窝，在该区域采用经上颌入路切除神经鞘瘤似乎并非禁忌证。
