Multimodal imaging in a case of atypical choroidal osteoma: a 1-year follow-up

Choroidal osteomas are rare, benign, ossifying tumors of the choroid that are either flat or slightly elevated, located juxtapapillary, and usually have a well-defined geographic border. We describe a case of choroidal osteoma in a young male with atypical features, including a high elevation of the lesion, blurred margins, and a location away from the optic disc. We also describe the role of multimodal imaging, which allowed us to distinguish an atypical variant of choroidal osteoma from other choroidal mass lesions.
