外伤后脑膜脑膨出致眼球突出1例

A case of proptosis by traumatic delayed meningo-encephalocele

1病例报告 患者,男,17岁,因“渐进性左眼球突出伴动眼及视物障碍2个月余”于云南省第二人民医院眼科首诊。入院CT示：左侧额窦、筛窦软组织密度灶,左眶顶壁、内侧壁骨质受压、吸收,病灶凸向左眼眶,左眼球前突、外移,左上直肌和内直肌受压、移位,病灶CT值约36HU,增强扫描未见明显强化;

A case of traumatic delayed meningo--encephalocele suffered orbital fracture, but bony defects in frontal sinus had not been found on CT scanning. We treated the patient with surgery of intranasal endoscopy and repaired the skull base defect successfully during the first attempt. There was no recurrence in 10 months followed up. The leak site may not correlate with imaging in traumatic delayed meningo-encephalocele by comparing operative findings with the imaging estimate and endoscopy. Therefore, endoscopical approaching is effective in seeking and treatment.
