Glomangiopericytoma is an uncommonly encountered tumor of the nose and paranasal sinuses, accounting for <0.5% of all sinonasal tumors. Extension of these lesions to the anterior or middle cranial fossa is rare. When this occurs, diagnosing glomangiopericytoma is extremely challenging, as it is often confused with other anterior skull base tumors.
We report a case of a giant glomangiopericytoma localizing into the cavernous sinus in a 48-year-old female who presented with mild left-sided ptosis for 48 months. The lesion simulated an intracavernous meningioma on preoperative imaging. An expanded endoscopic endonasal approach was used to debulk the portion of the lesion in the medial compartment of the cavernous sinus. Postoperatively, the patient's ptosis resolved completely, and no new deficits were sustained.
This is the only case of glomangiopericytoma localizing solely to the cavernous sinus reported to date.
血管外皮细胞瘤是一种在鼻腔和鼻窦中罕见的肿瘤,占所有鼻窦肿瘤的比例不到0.5%。这些病变扩展至前颅窝或中颅窝的情况很少见。当这种情况发生时,诊断血管外皮细胞瘤极具挑战性,因为它常与其他前颅底肿瘤相混淆。
我们报告了一例48岁女性的巨大血管外皮细胞瘤,该肿瘤位于海绵窦,患者出现左侧轻度上睑下垂48个月。术前影像学检查显示该病变类似海绵窦内脑膜瘤。采用扩大的鼻内镜经鼻入路切除海绵窦内侧腔室的部分病变。术后,患者的上睑下垂完全消失,且未出现新的神经功能缺损。
这是迄今为止报道的唯一一例仅局限于海绵窦的血管外皮细胞瘤病例。
