High-frequency radio-wave ablation of osteoid osteoma in the lumbar spine

This report describes a presumed choroidal granuloma with vitreous hemorrhage resembling choroidal melanoma. A healthy 31-year-old man, who had progressive vision loss in the right eye during 1 month, was found to have a yellow-white juxtapapillary choroidal mass. Fluorescein angiography demonstrated a choroidal neovascular membrane over the lesion. There was focal persistent hypofluorescence in the late phase of fluorescein angiography. The thickness of the lesion increased from 3.0 mm to 7.1 mm during 1 month. Subretinal and vitreous hemorrhage developed. The patient was suspected to have a choroidal granuloma and choroidal neovascular membrane, and was treated with oral steroids. Ten months later, the vitreous blood cleared completely with an attached retina. Control of inflammation may have a role in the treatment of idiopathic choroidal granulomas and some choroidal neovascular membranes secondary to ocular inflammation.
