Schwannomas are slowly growing, well capsulated, benign tumors. Involvement of vestibular nerve is most commonly followed by trigeminal nerve. Trigeminal schwannoma is rare entity, and cystic degeneration with intraorbital extension of trigeminal schwannoma is even rarer. These tumors occur in fourth and fifth decades of life and patients have variable presentation depending on which cranial compartment is involved. Orbital schwannoma usually presents with proptosis with or without vision loss. We are reporting such a rare case of solid cystic trigeminal schwannoma with intraorbital extension through superior orbital fissure that was removed surgically.
施万细胞瘤是生长缓慢、包膜完整的良性肿瘤。最常累及前庭神经，其次是三叉神经。三叉神经施万瘤是一种罕见的疾病，伴有眶内扩展的三叉神经施万瘤囊性变则更为罕见。这些肿瘤多发生于40至50岁，根据受累的颅腔不同，患者的表现各异。眼眶施万瘤通常表现为眼球突出，可伴有或不伴有视力丧失。我们报告了这样一例罕见的实性囊性三叉神经施万瘤，它经眶上裂向眶内扩展，已通过手术切除。
