Bilateral Choroidal Osteoma in a Teenage Girl With Chronic Posterior Scleritis.

A 14-year-old girl with bilateral chronic posterior scleritis was referred to us for poor control of ocular inflammation. There was an incidental finding of choroidal osteoma bilaterally whereby the choroidal mass in her right eye demonstrated a significant tumor growth in a short duration of two months. The right eye choroidal tumor was orangy in color with a well-defined margin, two-disc diameter in size, and located at the macula encroaching the fovea. Multimodal imaging assessments, including serial color fundus photo, enhanced depth imaging optical coherence tomography (EDI-OCT), and B scan ultrasonography monitoring, confirmed a continuous rapid growth of choroidal osteoma with episodes of scleritis flare-ups. Furthermore, intolerance toward second-line immunosuppressants and loss of follow-ups during the coronavirus disease 2019 (COVID-19) pandemic lockdown led to frequent relapses of her posterior scleritis. Therefore, a new treatment plan was designed, and close monitoring of choroidal osteoma growth and control of posterior scleritis were initiated. Subsequently, bilateral posterior scleritis remained quiescent, and her vision remained stable with stagnant growth of choroidal osteoma.
