摘要
一位36歲女性患者在右眼視乳頸下方發現一個黃白色、啞鈴狀、有鮮明地圖狀邊緣，扁平而有輕微隆起的脈絡膜病灶。螢光血管攝影顯示病灶區有瀰漫性顆粒狀之過螢光，而其中央有數個小圓形之低螢光區。超音波、X光及頭部電腦斷層攝影檢查都顯示眼球後壁有一與骨質緻密度一致之腫塊。符合Gass所提脈絡膜骨瘤之診斷。病人於初診時視力6/6，視野檢查有一與病灶位置對稱之視野缺損，但經10個月後出現黃斑部出血，視力降為6/12。

A yellowish-white, well-defined choroidal lesion was noted in the right eye of a 36-year-old Chinese woman which was inferior to the optic disc with geographic borders. The visual acuity was 6/6 at the first visit. Visual field examination revealed a compatible visual field defect. Fluorescein angiogram showed diffuse granular hyperfluorescence over the tumor area with some round hypofluorescent areas at the center. In the echogram, X-ray film and computerized tomogram, a choroidal mass with bone density was revealed. The findings supported a diagnosis of choroidal osteoma as Gass proposed. Ten months later, macular hemorrhage happened and the visual acuity was decreased to 6/12.
