Follicular Thyroid Carcinoma With Late Choroidal Metastases

ABSTRACT
To report a case of thyroid follicular carcinoma with bilateral choroidal metastases. Follicular thyroid carcinoma is the second most common thyroid carcinoma. Distant metastases are not rare, but both globe and orbit metastasis secondary to follicular or other th yroid carcinomas are very rare. A 54-years old woman was opearated for multinodular goitre however thyroid follicular carcinoma was confirmed with histologic examination. Although repeated radioiodine therapies, distant metastases progressed. Patient complained of sudden sight loss in the right eye and examination revealed metastatic tumors in both orbits. The choroidal masses had the typical appearences of a metastatic lesion. Chemotherapy, external-beam radiotherapy to left eye and an urgent enucleation operation to right eye were planned Thyroid follicular carcinoma can metastasize to choroid and it is, thus, suggestable that ophtalmologic controls be included in routine preoperative and postoperative clinical examinations of thyroid carcinoma patients.
