Choroidal osteoma is a rare clinical entity of unknown etiology. It is a benign ossifying tumor characterized by mature bone replacing choroid. It typically affects young females, unilaterally. Vision loss occurs mainly due to photoreceptor degeneration secondary to decalcification and/or development of choroidal neovascularization, especially if located near the macular area. We present a case of an old woman with bilateral choroidal osteomas identified incidentally. An 84-year-old Caucasian woman who was asymptomatic, without clinical features suggestive of choroidal osteoma, was referred to our hospital for a follow-up visit. On the fundus examination, both eyes showed a suspected lesion. B-scan ultrasound demonstrated bilateral highly reflective calcified lesions within the choroid, with an evident cone of shadow, suggestive of choroidal osteoma. Further investigations have performed to confirm the diagnosis. Although the literature reports a more common one-sidedness and typical manifestation of choroidal osteoma in the teenage years, our case report refers to bilateral choroidal osteomas in an elderly woman.
脉络膜骨瘤是一种病因不明的罕见临床病症。它是一种良性骨化性肿瘤，其特征是成熟骨取代脉络膜。它通常单侧累及年轻女性。视力丧失主要是由于脱钙和/或脉络膜新生血管形成继发的光感受器变性，特别是当病变位于黄斑区附近时。我们报告一例偶然发现双侧脉络膜骨瘤的老年女性病例。一名84岁无症状的白种女性，无提示脉络膜骨瘤的临床特征，因随访就诊被转诊至我院。眼底检查时，双眼均发现可疑病变。B超显示脉络膜内双侧高反射性钙化病变，伴有明显的声影，提示脉络膜骨瘤。为确诊进行了进一步检查。尽管文献报道脉络膜骨瘤在青少年中更常见的是单侧性和典型表现，但我们的病例报告涉及一名老年女性的双侧脉络膜骨瘤。
