A healthy 7-year-old boy was referred after being seen by multiple specialists and having no clear diagnosis for bilateral white papillomacular lesions (Figure, left). On enhanced depth imaging optical coherence tomography, there was subretinal fluid involving the right fovea and a layered lamellar appearance of the choroid. B-scan ultrasonography demonstrated highly reflective choroidal lesions with posterior shadowing consistent with calcium (Figure, right). The diagnosis of choroidal osteoma was established. This benign lesion is found most frequently in young adult female patients. It is important to remember that choroidal osteoma can also occur in children and may be bilateral.
