A 65-year-old woman presented with a 3 month history of right eye discomfort and protrusion. Examination revealed right proptosis with hypoglobus and diplopia in extremes of upgaze. Computed tomographic scanning revealed a large extraconal mass in the superotemporal orbit. The mass was excised through an extended superior skin crease incision. Histopathology revealed a benign tumour of Schwann cell origin showing advanced cystic degeneration, the so-called 'ancient schwannoma'. The authors could find only two previously reported cases of such tumours arising in the orbit.
一名65岁女性出现右眼不适和突出3个月的病史。检查发现右眼眼球突出、眼球下斜，上视极度时出现复视。计算机断层扫描显示颞上眶有一个大的眶锥外肿块。通过扩大的上睑皮肤皱襞切口切除肿块。组织病理学显示为起源于施万细胞的良性肿瘤，伴有晚期囊性变，即所谓的“陈旧性神经鞘瘤”。作者仅能找到两例先前报道的发生在眼眶的此类肿瘤病例。
