Abstract

Choroidal osteoma is a rare benign ossifying tumour of the choroid, typically found in healthy young females in the second or third decade. We report a case of a juxtapapillary choroidal osteoma as an incidental finding in a 9-year-old Indian male. Fundus examination revealed an elevated, orange yellow geographic lesion inferior to the optic disc. B-scan ultrasound showed an elevated choroidal mass inferior to the optic disc, with high-intensity echo spike. A characteristic shadowing could be seen posterior to the lesion, giving the appearance of a pseudo-optic nerve. Spectral-domain optical coherence tomography (SD-OCT) showed an increased sub-foveal choroidal thickness with a central tumour thickness of 576 um and absence of choroidal vessels. Reports of choroidal osteoma in children are relatively rare and, when present, necessitate exclusion of other non-pigmented lesions of the posterior pole such as retinoblastoma, congenital retinochoroidal coloboma and metastatic calcification.
