Clinicopathological report: bilateral choroidal metastases from papillary thyroid cancer

Bilateral uveal metastases from papillary thyroid carcinoma are extremely rare. A 36-year-old woman with a 12-month history of papillary thyroid carcinoma presented with sudden loss of visual acuity and fields in the left eye. An examination and B-scan revealed a large, solid choroidal lesion in the left eye causing exudative retinal detachment. A small solid mass was also observed in the right eye fundus. Following left eye enucleation, immunohistopathology confirmed metastatic papillary thyroid carcinoma. The authors report the third known case of bilateral choroidal metastases.
