Choroidal Osteoma with Focal Choroidal Excavation Masquerading as Active Vogt-Koyanagi-Harada: A Case Report

This case illustrates a rare instance of choroidal osteoma masquerading as a posterior relapse of VKH disease. It emphasizes the critical importance of differentiating inflammatory from non-inflammatory choroidal lesions in patients with a history of uveitis. Careful interpretation of multimodal imaging is essential to avoid misdiagnosis, prevent unnecessary immunosuppressive treatment, and reduce associated risks, ultimately leading to improved patient outcomes.
