Osteoma coroideo secundario a trauma ocular

the choroidal osteoma is a benign bony tumor described for the first time in 1978 by gass and collaborators. it is generally unilateral, with juxtapapillary localization and more frequent in young adult females. it presents unknown etiology, but it is associated to different factors as inflammatory processes, congenital malformations, hormonal alterations and ocular traumas among others. the patient was a 54 year-old woman with a personal history of rheumatic fibromyalgia (osteoarthrosis and osteoporosis) and hypertension. her ophthalmological antecedent showed myopia and arteriolosclerotic retinopathy. at the beginning of the year, she suffered a traffic accident and was injured in her limbs and periocular region. after this, she began feeling blurred vision of the right eye and she went to our service 6 months later. she was performed an ophthalmologic exam. it was found that the right eye had visual acuity of 0.4, and after correction it reached 1.0 .funduscopy revealed vascular thinness, incomplete posterior vitreous detachment, and a white-orange lesion of 3 papillary diameters that involved inferior temporary arcade with well-defined borders. an angiography was performed, which showed sustained hyperfluorescence and non neovascularization; and the optic coherence tomography revealed a halo of serous retinal detachment. additionally, the ocular ultrasound yielded a high reflectivity echogenic image that involves choroids with posterior acoustic shadow. it is for this reason that we affirm the traumatic etiology of the lesion. this is a rare pathology that should be diagnosed by imaging techniques. notably, it is secondary to an ocular trauma.
