Abstract

Choroidal osteoma is a rare benign tumor which is found in the posterior pole of the eye. We herein describe multimodal imaging in two cases of choroidal osteoma. Fundus of our first case showed a yellowish-orange colored subretinal lesion at the posterior pole. Multicolor imaging highlighted the lesion with greenish hue. Infrared reflectance showed hyporeflectance. A dense echogenic plaque persisting in lower gain was noted on B-scan. FFA showed hyperfluorescence with corresponding hypocyanescence on ICG. EDI OCT showed an increase in choroidal thickness with elevated retinal pigment epithelium. The second case showed choroidal osteoma with active choroidal neovascular membrane that responded to intravitreal injection of Ranibizumab.
脉络膜骨瘤的多模式成像
脉络膜骨瘤是一种罕见的良性肿瘤,见于眼球后极。我们在此描述两例脉络膜骨瘤的多模式成像。我们第一个病例的眼底显示后极有一个黄橙色的视网膜下病变。多色成像显示病变呈绿色。红外反射率呈低反射率。在B型扫描上发现一个持续较低增益的致密回声斑块。FFA在ICG上显示出高荧光和相应的低氰。EDI OCT显示脉络膜厚度增加,视网膜色素上皮升高。第二例为脉络膜骨瘤,有活性脉络膜新生血管膜,对玻璃体内注射雷尼珠单抗有反应。
