Summary
Choroidal osteoma, a rare benign ossifying tumor, presents as a subretinal lesion. Multimodal imaging aids diagnosis, and conservative management with monitoring is typical for this condition.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Choroidal osteoma is a rare, benign ossifying tumor of the choroid.
- It predominantly affects young individuals and can be associated with systemic inflammatory or immune-mediated conditions.
Purpose of the Study:
- To describe the clinical presentation, multimodal imaging findings, and management of choroidal osteoma patients.
- To highlight the diagnostic utility of various imaging modalities in choroidal osteoma.
Main Methods:
- Retrospective case series of three patients (four eyes) diagnosed with choroidal osteoma.
- Comprehensive ophthalmic examination including fundus photography, B-scan ultrasonography, optical coherence tomography (OCT), fluorescein angiography (FA), OCT angiography, and computed tomography (CT).
Main Results:
- Patients presented with decreased vision or vitreous floaters.
- Characteristic yellowish-white or orange peripapillary subretinal lesions were identified.
- Multimodal imaging revealed calcified choroidal lesions with specific features on ultrasonography, CT, and OCT. No active choroidal neovascularization was observed at presentation. Associated conditions included systemic lupus erythematosus and retinal vasculitis.
Conclusions:
- Choroidal osteoma is a rare benign ossifying tumor often associated with inflammatory conditions.
- Multimodal imaging is crucial for diagnosis and monitoring of choroidal osteoma.
- Conservative management with long-term surveillance is recommended due to potential complications like decalcification and choroidal neovascularization.
