[Ocular metastasis revealing ductal carcinoma of the breast].

We report the case of a 56-year old female patient, with no particular past medical history, presenting at the Emergency Department with decreased visual acuity in the right eye occurred 2 weeks before. Ophthalmologic examination showed reduced visual acuity to perception of hand movements. Fundus examination showed serous retinal detachment associated with subretinal mass occupying almost the entirety of the vitreous cavity (A). B-mode scan was performed which objectified isoechoic choroidal mass (B) with vascularization on Doppler (C) without any excavation, measuring 18 mm along its longer axis associated with serous detachment of the retina, highly suggestive of ocular metastasis. General assessment was performed and, in particular, mammography which revealed the presence of a nodule in the right breast (stage 4 according to BI-RADS Classification). Thoraco abdominopelvic and brain CT scan performed during staging evaluation showed many brain, bone and liver metastases. The diagnosis of metastatic breast cancer was made and the patient was referred to the Department of Oncology for specialist treatment. Ocular metastases are the most common intraocular tumors. Breast tumors are the main cause of choroidal metastases, justifying comprehensive assessment to highlight these intraocular tumors.
