Bilateral Choroidal Osteomas in Rosai

The purpose of this case report is to describe a case of bilateral choroidal osteomas in Rosai-Dorfman disease, a rare pseudolymphomatous disorder. A case report was conducted. A middle-aged man with biopsy-proven Rosai-Dorfman disease presented with chronic poor vision of the left eye. Clinical examination showed bilateral white lesions with scalloped edges, and optical coherence tomography revealed hyporeflective choroidal lesions. Ultrasonography confirmed the lesions as choroidal osteomas. The patient was observed and remains stable after 9 months of follow-up. Bilateral choroidal osteomas in the setting of Rosai-Dorfman disease are an uncommon finding. While the best treatment for the disease remains unclear, observation is a reasonable option for stable patients
