Choroidal osteoma is a rare benign ossifying tumor with unknown etiology, typically affecting young females. However, our case report involves bilateral choroidal osteomas in an elderly woman.
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.
