Skull base and intracranial cystic schwannomas are rare tumors. To our knowledge, a cystic schwannoma involving the sphenoid sinus has not been previously reported. The location and fluid-filled nature of the lesion resulted in an erroneous preliminary diagnosis of a destructive sphenoid sinus mucocele. Endoscopic biopsy and decompression established the correct diagnosis and reversed a progressive visual loss until definitive surgical removal of the lesion was accomplished. Diagnostic evaluation, histologic findings and management strategies are discussed.
颅底及颅内囊性神经鞘瘤是罕见肿瘤。据我们所知，此前尚无蝶窦内囊性神经鞘瘤的报道。病变的位置及充满液体的特性导致初步误诊为侵袭性蝶窦黏液囊肿。内镜活检及减压明确了正确诊断，并扭转了视力渐进性丧失的情况，直至最终手术切除病变。本文讨论了诊断评估、组织学发现及治疗策略。
