Summary
A rare choroidal osteoma in a 56-year-old man spontaneously resolved over three years. This benign bone tumor of the choroid, initially treated for associated neovascularization, showed complete decalcification and disappearance on follow-up.
Area of Science:
- Ophthalmology
- Medical Imaging
- Oncology
Background:
- Choroidal osteomas are rare, benign bone tumors in the posterior uvea.
- They can present with complications such as subretinal neovascularization (SRNV).
- Treatment of SRNV in choroidal osteomas can be challenging.
Observation:
- A 56-year-old male presented with a posterior pole choroidal osteoma.
- Initial treatment for subretinal neovascularization with laser photocoagulation was unsuccessful.
- Recurrent neovascularization occurred, and the tumor showed progressive thinning over three years.
Findings:
- The choroidal osteoma completely resolved within 15 months after initial thinning was observed.
- Ultrasonography demonstrated complete decalcification of the tumor.
- The resolution left an area of retinal pigment epithelial and choroidal atrophy.
Implications:
- This case suggests that choroidal osteomas may undergo spontaneous regression and decalcification.
- Understanding the natural history of choroidal osteomas is crucial for management strategies.
- Further research is needed to elucidate the mechanisms behind spontaneous resolution in these benign tumors.
