摘要

本文報告一位四十歲女性病人主訴兩星期來左眼視力有喪失的現象。於眼科理學檢查後發現，左眼視力僅存手動感且無法矯正、同時其亦有色覺變差及瞳孔光反射異常之情形。眼底檢查顯示左眼視神盤輕微水腫但其邊緣仍可辨識、同時合併輕微黃斑部病變。由於視野檢查結果為左眼側半盲，我們隨後安排眼窩及腦部電腦斷層及核磁共振掃瞄檢查，以確定是否為腫瘤造成之壓迫現象。結果顯示左側視神經略為腫大且視神經孔、前蝶鞍床突、及海綿竇有腫瘤浸潤之現象。轉至神經外科手術後、最終之病理報告結果為視神經腦膜瘤。而病人於術後眼科回診時、左眼視力已降至無光感。

We present a 40-year-old female patient who complained of loss of vision in her left eye for two weeks. On ophthalmic examination, the best corrected visual acuity in the left eye was reduced to hand motion. The color sensation in her left eye was also impaired. Her left pupil showed mid-dilatation with signs of RAPD. Fundal examination revealed that the left disc was mildly edematous; however, its margin was not blurred and the appearance of mottled RPE was also noted in the left macula. On visual field examination, temporal hemianopsia of the left eye was noted. Subsequent orbital and brain CT scan and MRI showed a tumor involving the left optic canal, anterior clinoid process of the sphenoid and the cavernous sinus. She was then transferred to the neurosurgical department under the suspicion of an optic nerve tumor with intracranial involvement. The pathology of the specimen excised confirmed a proliferation of meningothelial cells, which is consistent with optic nerve meningioma. Postoperatively, her visual acuity in the left eye worsened to no light perception.
