Choroidal metastasis as a rare feature of papillary thyroid carcinoma

Department of Ophthalmology, Hôpitaux Universitaires de Strasbourg, Nouvel Hopital Civil, France Abstract Introduction Choroidal metastasis is a very rare clinical manifestation of thyroid cancer. The goal of our work is to report a case of late choroidal metastasis from papillary thyroid carcinoma. Case report A 59-year-old woman who had been treated for papillary thyroid carcinoma 3 years earlier presented for evaluation of vision loss in the right eye. A fundoscopic examination revealed a choroidal mass which had the typical characteristics of a metastatic lesion. After exclusion of any other neoplastic lesion, metastatic lesion from papillary thyroid carcinoma was diagnosed. The patient was treated with a combination of brachytherapy and chemotherapy. Despite this treatment, the patient complained about two other metastatic lesions (lung and hip) a few months later. Conclusion Papillary thyroid carcinoma can metastasise to the choroid many years after the initial diagnosis.
